Cracking a math problem? Practicing Latin? Splitting an atom? This room is a side spot you can pop into to go back and forth on your homework problems.

2017-12-04 02:10:06 UTC

2017-12-04 03:25:29 UTC

I know there's a lot of smart people here so I'm sure we can help each other out!

2017-12-04 03:25:55 UTC

In a past life I was a college math instructor and I still love the stuff so if there's anything in that area I can help with send me a ping!

2017-12-04 03:42:12 UTC

Im an junior electrical engineering student, also available for homework help !

2017-12-04 05:16:00 UTC

@givemetheafd Have you taken a signals and system class?

2017-12-04 17:02:40 UTC

What is 10 x 10?

2017-12-04 23:58:57 UTC

4

2017-12-05 01:08:58 UTC

I was a nuclear reactor operator. I can help with the splitting the atom questions.

2017-12-05 05:21:04 UTC

Any college kids that need help writing any papers, I'm here to help!

2017-12-05 14:17:19 UTC

@Deleted User i have taken signal processing, but not the junior level class yet

2017-12-06 01:38:49 UTC

Hey guys, just wanted to quickly introduce myself as someone you can go to for academic assistance. If you need help with history, humanities, literature, or writing feel free to reach out to me either on here or my DM's.

2017-12-11 18:09:23 UTC

So, it's finals today and I have a problem. I had all A's this semester, and a lot of them dropped to B's, C's, and one F... I don't know what happened, but I feel like my brain has been fried this month, it seems so hard to focus on work and study like I used to at the beginning of the semester. What can I do?

2017-12-11 18:09:33 UTC

Is this burnout?

2017-12-11 18:10:15 UTC

@The Eternal Anglo Where are you studying?

2017-12-11 18:10:30 UTC

As in, physical location. Are you near a computer or a laptop when studying?

2017-12-11 18:10:59 UTC

I study at my home PC, in the master bedroom

2017-12-11 18:11:11 UTC

All my classes require online attention

2017-12-11 18:11:19 UTC

What subjects are you taking?

2017-12-11 18:11:41 UTC

(in general)

2017-12-11 18:12:11 UTC

Intermediate Algebra, Python, Microcomputer application (Microsoft applications) visual arts, and intermediate english

2017-12-11 18:12:45 UTC

Are you finding yourself neglecting one or more subjects until the deadline becomes uncomfortably close?

2017-12-11 18:13:25 UTC

Yupp, mainly with math/microsoft applications

2017-12-11 18:13:36 UTC

(first year student btw)

2017-12-11 18:13:51 UTC

Are you familiar with the term "context switching?"

2017-12-11 18:14:19 UTC

Not entirely

2017-12-11 18:14:42 UTC

OK, so here's what I think is happening. It's the same problem I had throughout my college years.

2017-12-11 18:14:54 UTC

You're studying on your PC, seems like that's by necessity

2017-12-11 18:15:07 UTC

but there are so many distractions available

2017-12-11 18:15:16 UTC

Discord, Twitter, who knows what else

2017-12-11 18:15:44 UTC

So as soon as the material becomes boring or difficult to comprehend, your brain seeks the easier novelty available through these other mediums

2017-12-11 18:16:09 UTC

And then you jump to another subject in which you think it will be easier to accomplish something at the time.

2017-12-11 18:16:20 UTC

Is what I'm saying correct?

2017-12-11 18:18:06 UTC

Sounds right actually

2017-12-11 18:18:45 UTC

OK, so the first item of business is to limit distractions. Here's my advice for that.

2017-12-11 18:19:10 UTC

If all your study material is online, that's a big challenge. It's much easier to focus on printed material.

2017-12-11 18:19:30 UTC

If you can obtain printed material, I highly recommend it. But it's not a necessity.

2017-12-11 18:19:57 UTC

What you have to do is, before you sit down to study, make a list of what you want to accomplish in each course.

2017-12-11 18:20:32 UTC

So in today's Python session you're going to understand the concept of generators and write some example code or complete the exercises.

2017-12-11 18:20:45 UTC

And that's **all** you're going to allow yourself to do once you start

2017-12-11 18:21:13 UTC

Everything else gets turned off. Use a stripped-down browser, remove all other devices from the area.

2017-12-11 18:21:27 UTC

If you cheat, you're only cheating yourself.

2017-12-11 18:22:02 UTC

Once you check it off, take a break. Fifteen minutes is usually ideal. Get up, walk around, rest your eyes, check your various social media, then knock out the next item.

2017-12-11 18:22:48 UTC

When you context switch frequently, you don't allow yourself to build up a foundation for learning, understanding, and retaining material. It all gets flushed out as soon as you switch to some other distraction or task.

2017-12-11 18:23:48 UTC

If you have an old laptop laying around, it might be worth it to do a fresh install of your preferred OS on it, and ONLY install the bare minimum you need to use it for your coursework

2017-12-11 18:23:59 UTC

and take it somewhere quiet, like the library or bookstore

2017-12-11 18:24:26 UTC

that way you're in a place that's not as comfortable to you. That actually improves focus in my experience.

2017-12-11 18:25:12 UTC

I never studied in my dorm room. I always went to the library. But all my material was printed back then (2000-2004).

2017-12-11 18:27:23 UTC

It may be a good idea for me to print out what I can for studying purposes as well, and the 15 minute break seems good, actually

2017-12-11 18:27:43 UTC

yeah, it's very important to take breaks.

2017-12-11 18:27:54 UTC

going for a walk was the secret sauce for me

2017-12-11 18:29:21 UTC

It's going to be very difficult at first not to get distracted, but that's where the checklist will help you.

2017-12-11 18:29:37 UTC

The checklist says "This is the only thing I'm allowed to do right now."

2017-12-11 18:30:51 UTC

I recently studied for a math test for 12 HOURS... still did not do well on the test itself. We live in a pretty cozy neighborhood, so I could go walking.

2017-12-11 18:31:05 UTC

I really like this checklist idea actually!

2017-12-11 18:31:10 UTC

Right, but did you really study?

2017-12-11 18:31:24 UTC

If you're checking your phone every 10 minutes, you're just treading water.

2017-12-11 18:31:54 UTC

(I have two STEM master's degrees, I've been in exactly the same situation 😃 )

2017-12-11 18:32:25 UTC

quick anecdote: when I was in calculus, I "studied hard"

2017-12-11 18:35:22 UTC

Taking notes on all of this good information, also that is impressive my dude!

2017-12-11 18:35:40 UTC

We have a library that I can use, and maybe normie starbucks might work, too

2017-12-11 18:37:44 UTC

I appreciate all the advice you've given mate!

2017-12-11 18:52:27 UTC

but I didn't strive to understand what I was doing. As soon as I got a rudimentary understanding, I immediately went on to other subjects or distractions

2017-12-11 18:52:46 UTC

needless to say, I got rekt later on in the course because I did not have the prior fundamentals down.

2017-12-11 18:53:25 UTC

So that summer, I went back through the text. I worked graveyard at a factory, and we got a few breaks every shift.

2017-12-11 18:54:04 UTC

So on the first break, I would very slowly and deliberately read the explanation at the beginning of the section. Then I would write down some practice problems.

2017-12-11 18:54:24 UTC

When the line went down (which happened a lot that summer), I would pull out the practice problems and work them on the scrap cardboard

2017-12-11 18:55:07 UTC

so that fall when I took the next course in the calc sequence, I did just fine because I took the time to get a full understanding

2017-12-11 18:55:35 UTC

it didn't take much time, but it did take full concentration. you'll see once you eliminate distractions that concentration matters much more than time spent.

2018-01-12 04:34:59 UTC

I would be happy to help with mathematics (calc 2 and below), also EMT-Basic and Nursing Assistant questions as well.

2018-01-24 20:59:51 UTC

I am writing a rhetorical analysis for my writing class on this video. I need to both analyze the argument and the way the speaker presents as well as determine the credibility of the information presented

2018-01-24 21:01:23 UTC

Note: The primary goal here is to examine rhetoric, how effectively the speaker’s ideas are communicated, not necessarily to agree or disagree with the speaker.

2018-01-24 21:02:03 UTC

But naturally I can be contrarian and present evidence against the speaker

2018-01-24 21:03:37 UTC

Dude runs an NGO lol

2018-01-24 21:03:58 UTC

He's jewish too I'm weak

2018-01-25 19:13:25 UTC

@here Anyone know anything about bond valuation ?

2018-01-25 19:13:56 UTC

@BryceB-ND Yes! What's the question?

2018-01-25 19:14:04 UTC

Also yes

2018-01-25 19:14:06 UTC

If you have a floater and an inverse floater derived from your collateral, is the coupon rate of the collateral the weighted average of the floater and inverse floater?

2018-01-25 19:14:47 UTC

2018-01-25 19:15:08 UTC

I got 8%

2018-01-25 19:15:20 UTC

I used this "

https://cdn.discordapp.com/attachments/387060078433271808/406165159296499715/unknown.png

2018-01-25 19:15:26 UTC

I used this as my example to go off of.

2018-01-25 19:17:12 UTC

I also want to check my work on computing the dirty and clean price as well as accrued interest of another example in case you both have an idea on that as well

2018-01-25 19:17:20 UTC

This is a similar example.

2018-01-25 19:17:33 UTC

Lemme find my calculator

2018-01-25 19:17:37 UTC

^uploading

2018-01-25 19:17:39 UTC

ty

2018-01-25 19:21:59 UTC

Pretty sure 8 is correct

2018-01-25 19:22:48 UTC

Would just be the average

2018-01-25 19:22:55 UTC

Ok good that's what i had thought

2018-01-25 19:23:18 UTC

What's the other question?

2018-01-25 19:23:30 UTC

3. Assume the original maturity a bond with face value $1000 is 8 years. The annualized
yield to maturity for the bond is 6.25% and its annual coupon rate is 7.5% being
2
semiannually paid. The bond was issued on 8/1/2015, and bought on 12/1/2017.
Compute the following:
(1) dirty price, (2) clean price and (3) accrued interest. (7 points)

2018-01-25 19:24:06 UTC

I calculated 1058.76 for dirty price, 1046.26 for clean and 12.5 for accrued interest.

2018-01-25 19:24:30 UTC

I understand this problem, what I don't get is how to calculate the accrued interest because I don't know how to determine the intervals of the semi annual interest payments.

2018-01-25 19:26:26 UTC

Hmm. Send pic of question

2018-01-25 19:27:03 UTC

2018-01-25 19:28:39 UTC

2 min

2018-01-25 19:31:40 UTC

Ok so the equation for AI might be

cash flow (1-(days/total days in coupon period))
Idk that helps

2018-01-25 19:33:28 UTC

Yeah I know that much, thank you, I'm having trouble just discerning the days since the last coupon payment from the dates given is all.

2018-01-25 19:36:15 UTC

Bonds usually pay interest on the first day of January and July

2018-01-25 19:36:31 UTC

That's usually what semiannual implies.

2018-01-25 19:36:37 UTC

Ok.

2018-01-25 19:36:38 UTC

Ty

2018-01-25 20:26:45 UTC

@SamanthaM awesome, I think this is the first homework help of the new academic channels!

2018-01-29 00:29:26 UTC

Would anyone @here be willing to read my rought draft for a paper I'm writing on this video:

2018-01-29 00:31:37 UTC

Also any specific sources to help back up my statements would be appreciated

2018-01-29 00:37:17 UTC

@StrawberryArmada I suggest putting the paper into a google doc, and creating a share link where anyone with the link can comment on (but not edit) the document

2018-01-29 00:39:17 UTC

Good idea

2018-01-29 00:46:18 UTC

This should work

2018-01-29 00:46:20 UTC

Halp pls

2018-01-29 00:46:28 UTC

:)

2018-01-29 01:22:09 UTC

@StrawberryArmada Alright dude I looked over it, left my comments and some sources I found. Hopefully someone else can give it a once over as well @here

2018-01-29 01:22:32 UTC

Thanks mate. I still have a week before the finally draft

2018-01-29 01:25:17 UTC

yw!

2018-01-29 02:52:36 UTC

Anyone able to help with an algebra problem? Pretty basic

2018-01-29 02:53:17 UTC

@Warren H shoot

2018-01-29 02:53:32 UTC

9u = 6/5

2018-01-29 02:53:47 UTC

https://cdn.discordapp.com/attachments/387060078433271808/407367696531849226/image.jpg

2018-01-29 02:53:49 UTC

How do i get to 2/15?

2018-01-29 02:54:00 UTC

Multiply both sides by 5

2018-01-29 02:54:10 UTC

so on the left you have 45 u

2018-01-29 02:54:43 UTC

an the right the 5 on the bottom cancels out with the 5 on the top you just multiplied

2018-01-29 02:54:52 UTC

so 45u = 6

2018-01-29 02:55:03 UTC

then divide both sides by 45

2018-01-29 02:55:09 UTC

so u = 6/45

2018-01-29 02:55:24 UTC

6 is 2\*3, and 45 = 15\*3

2018-01-29 02:55:49 UTC

so u = (2\*3)/(15\*3)

2018-01-29 02:56:06 UTC

the 3 on top and bottom cross out

2018-01-29 02:56:11 UTC

so u = 2/15

2018-01-29 02:57:08 UTC

@Warren H oh you want it the way they did it in the picture? it is similar:

2018-01-29 02:57:17 UTC

starting from 9u = 6/5

2018-01-29 02:57:29 UTC

Your way seems easier. There's was confusing as heck

2018-01-29 02:57:54 UTC

How did you know 15 x 3? Instead of 9x5?

2018-01-29 02:58:03 UTC

I'm bad with fractions lol

2018-01-29 02:58:32 UTC

I'll do it closer to the way they did it:
starting from 9u = 6/5
divide both sides by 9, so u = (6/5) * (1/9)

2018-01-29 02:58:42 UTC

so u = 6/(5*9)

2018-01-29 02:58:59 UTC

now 6 is 2\*3 and 9 is 3\*3

2018-01-29 02:59:12 UTC

so u = (2\*3)/(5\*3\*3)

2018-01-29 02:59:29 UTC

cross out a 3 on top and bottom

2018-01-29 02:59:39 UTC

Ohh okay.

2018-01-29 02:59:40 UTC

so u = 2/(5*3)

2018-01-29 02:59:44 UTC

so u = 2/15

2018-01-29 02:59:52 UTC

yep

2018-01-29 03:00:58 UTC

So I do that every time? Divide both sides by whatever the number is?

2018-01-29 03:01:46 UTC

Yep that will always work

2018-01-29 03:03:49 UTC

Awesome thanks. One more, this one is a negative number. I'm guessing it works the same?

2018-01-29 03:03:56 UTC

-4w = 6/7

2018-01-29 03:04:42 UTC

So divide both sides by -4 and I get 6/7 * 1/4? Or -1/4

2018-01-29 03:06:23 UTC

Yep:
divide both sides by -4, so w = 6/(7* -4)
6 is 2\*3 and -4 is 2\*-2
so w = (2\*3) / (7\*2\*-2)
then cross out the two on top and bottom
so w = 3/(7*-2)
so w = 3/(-14) or equivalently w = -3/14

2018-01-29 03:06:48 UTC

@Warren H the second one

2018-01-29 03:07:16 UTC

the negative sign stays with the number it is attached to

2018-01-29 03:10:14 UTC

Okay. So I got 3/7 the first time. But it's actually negative 3/14ths? Or -3 over 14?

2018-01-29 03:11:53 UTC

Yep. If you're asking if there is a difference between " negative 3/14ths vs -3 over 14" the answer is no, they have the same value

2018-01-29 03:12:39 UTC

Uh. Divide both sides by 9

2018-01-29 03:12:48 UTC

Oh geez

2018-01-29 03:12:55 UTC

I didn't see all this

2018-01-29 03:13:16 UTC

@Warren H One thing you might notice at the beginning: think about the equation -4w = 6/7

2018-01-29 03:13:39 UTC

one things you might notice is that the left side is -4 * w, and the left side is a positive number (specifically 6/7)

2018-01-29 03:13:55 UTC

that means w times a negative number is something positive

2018-01-29 03:14:41 UTC

so whatever w is, w must be some negative number, since -4 times a positive number would be negative.

2018-01-29 03:15:34 UTC

@Warren H This ^ might help as a kind of double check on your work, thinking what sign the final answer should have

2018-01-29 03:16:18 UTC

Okay yeah that makes sense.

2018-01-29 03:16:32 UTC

Ive been working a lot with linear equations

2018-01-29 03:18:57 UTC

@Warren H Yeah they are an important building block for a lot of things but there can be a lot to keep track of when getting used to them. Any thoughts in particular about linear equations? Let us know if you have any questions in the future!

2018-01-29 03:22:31 UTC

Haha I don't like them lol. The worst part of math for me is fractions, and finding missing numbers like x lol

2018-01-29 03:24:41 UTC

@Warren H haha yeah if you remember up there ^^^ the first way I wanted to solve for u... first thing I did was cross-multiplied the denominators because I don't like using fractions either if I don't have to.
Are you doing this for a math major?

2018-01-29 03:25:41 UTC

Yeah I will try to remember that

2018-01-29 03:26:14 UTC

And nope not at all. I'm majoring in media production. This is just a required core class. Even tho I took 4 years of math in high school 🙃

2018-01-29 03:28:27 UTC

@Warren H yep it's a common core req for almost everybody. welp, feel free to ping <@&387091385075105804> for help here throughout the semester!

2018-01-29 03:29:02 UTC

What's AE?

2018-01-29 03:29:13 UTC
2018-01-29 03:30:18 UTC

@Warren H Academic Expert, it pings everyone has volunteered to make themselves available to anyone asking questions. Lots of fellow students and teachers and former teachers here

2018-01-29 03:31:02 UTC

Although pinging @here works pretty well too

2018-01-29 03:31:58 UTC

Ah okay. That's good to know @ThisIsChris

2018-01-29 03:35:40 UTC

If you're still here I need some clarification on a problem that I think I did correctly but it's not approving

2018-01-29 03:36:00 UTC

@Warren H sure!

2018-01-29 03:36:33 UTC

-2z - 4z = 19+ 4

2018-01-29 03:37:53 UTC

left side is -6z
right side is 23
so -6z = 23
divide both sides by -6
so z = 23/(-6) or equivalently z = -23/6

2018-01-29 03:38:28 UTC

Oh

2018-01-29 03:38:37 UTC

lol I didn't do the signs right. I got 23/6 that's why

that'll do it

2018-01-29 03:39:16 UTC

😆 it's really hard to pay attention to that sometimes. Especially on timed exams

2018-01-29 03:40:19 UTC

Yeah, best thing I could advise is that whenever you see a negative sign ANYWHERE, double check at the end that the signs look right

2018-01-29 03:41:32 UTC

if all the numbers are positive then you probably don't have to be too careful. It's just when a negative sign appears, keep going, but walk through it again at the end

2018-01-29 03:42:21 UTC

Yeah that's a good way to check. I try my best lol

2018-01-30 04:34:55 UTC

Anyone @here to help with another math question?

2018-01-30 04:36:05 UTC

I might could. I haven't done math in a bit, but I can do things like the last question posted.

2018-01-30 04:37:15 UTC

I know the answer to this question, I'm just not sure how to solve to get to it

2018-01-30 04:37:44 UTC

6/9 * 3/12 squared - 4/6

2018-01-30 04:38:24 UTC

Is there an equals sign?

2018-01-30 04:39:01 UTC

No. supposed to solve it

2018-01-30 04:39:13 UTC

PEMDAS

2018-01-30 04:39:17 UTC

I meant I knew the answer

2018-01-30 04:39:21 UTC

Order of operations

2018-01-30 04:39:33 UTC

Yep did that

2018-01-30 04:40:11 UTC

Would a photo help for reference?

2018-01-30 04:40:15 UTC

Yes

2018-01-30 04:40:17 UTC

Yes.

2018-01-30 04:41:43 UTC

How do I get 1/24?

2018-01-30 04:42:13 UTC

When I multiply I get 54/1296 and i don't know how to reduce it because I'm bad at fractions

2018-01-30 04:44:07 UTC

Simplify 6/9 * 9/144

2018-01-30 04:44:19 UTC

The 9s cancel out

2018-01-30 04:44:33 UTC

54/54 = 1 and 1296/54 = 24

2018-01-30 04:44:39 UTC

And 6 goes into 144 24 times

2018-01-30 04:45:07 UTC

So cancelled out the 9s and divide 6/144 ?

2018-01-30 04:45:12 UTC

Is that mastering physics but for math

2018-01-30 04:45:16 UTC

Yes

2018-01-30 04:45:36 UTC

Or what @micbwilli said

2018-01-30 04:45:42 UTC

Either works

2018-01-30 04:45:57 UTC

Okay thanks @GetOffMyState#8267

2018-01-30 04:46:32 UTC

@micbwilli could you explain your way a bit more? How do you know that's what your supposed to do?

2018-01-30 04:48:52 UTC

2018-01-30 04:49:16 UTC

Both rely on what I did above with another example

2018-01-30 04:51:18 UTC

For your example think about how 6/9 * 9/144 = 9/9 * 6/144

2018-01-30 04:51:42 UTC

The 9/9 is 1 and can therefore be ignored

2018-01-30 04:51:50 UTC

If you are trying to reduce a fraction start with a common number and just work down.

So like with 54/1296, both are multiples or 9. I knew 54 was and I checked 1296. That's 6/144. I see if 6 can be used to divide 144, and since it can it becomes 1/24.

2018-01-30 04:52:46 UTC

6/144 = 6 /(24 * 6) = 6/6 * 1/24

2018-01-30 04:53:01 UTC

If you are unsure there to start diving top and bottom by 2 works if both numbers are even.

2018-01-30 04:53:17 UTC

^ this

2018-01-30 04:57:50 UTC

This is so complicated lol. Okay. So just find the GCD and then reduce it down.

2018-01-30 04:58:18 UTC

Or in this case, I could just divide 6/144

2018-01-30 04:58:25 UTC

Right?

2018-01-30 04:58:29 UTC

Yes

2018-01-30 04:58:56 UTC

Because the 9s happen to cancel out

2018-01-30 04:59:06 UTC

And if it's not a problem where it can cancel out then what?

2018-01-30 05:00:10 UTC

You can find the GCD

2018-01-30 05:01:22 UTC

Okay

2018-01-30 05:02:17 UTC

Thanks. Yall

2018-01-30 05:04:21 UTC

On another note, why do we teach PEMDAS when it should be PEDMSA?

2018-01-30 05:05:21 UTC

Multiplication and division are the same really

2018-01-30 05:05:35 UTC

Same with addition and subtraction

2018-01-30 05:05:50 UTC

So PEMDAS is easier to remember

2018-01-30 05:05:54 UTC

I've gotten answers wrong for doing multiplication first sometimes though

2018-01-30 05:06:06 UTC

And same with addition and sibtraction

2018-01-30 05:07:46 UTC

You might be breaking another rule or your teachers suck. Unless I’m forgetting something that’s wrong and you shouldn’t have been marked down

2018-01-30 05:09:13 UTC

If you are using a computer program it is probably programmed by someone diverse and doesn’t account for multiple but equally valid ways to the answer

2018-01-30 05:09:25 UTC

This class is online. The teacher just supervises. I followed PEMDAS as taught but when I did I kept getting answers wrong and when I viewed the solution they were doing division first

2018-01-30 05:09:28 UTC

Yes omg

2018-01-30 05:09:54 UTC

The worst part is that it only counts one answer correct. And if you don't get that correct it marks it wrong even if you understand the concept

2018-01-30 05:10:00 UTC

Bring it up in office hours, that’s BS

2018-01-30 05:10:11 UTC

And you cant practice the same problem twice

2018-01-30 05:10:19 UTC

It keeps changing it up
