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.

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

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!

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

@givemetheafd Have you taken a signals and system class?

What is 10 x 10?

4

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

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

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

<@&387091385075105804> Everyone who has offered to help others in any academic area has received an AE (Academic Expert) role. So if you have a question (homework or otherwise) you can preface it with <@&387091385075105804> to get the attention of this group!

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.

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?

Is this burnout?

@The Eternal Anglo Where are you studying?

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

I study at my home PC, in the master bedroom

All my classes require online attention

What subjects are you taking?

(in general)

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

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

Yupp, mainly with math/microsoft applications

(first year student btw)

Are you familiar with the term "context switching?"

Not entirely

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

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

but there are so many distractions available

Discord, Twitter, who knows what else

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

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

Is what I'm saying correct?

Sounds right actually

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

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

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

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

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

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

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

If you cheat, you're only cheating yourself.

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.

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.

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

and take it somewhere quiet, like the library or bookstore

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

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

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

yeah, it's very important to take breaks.

going for a walk was the secret sauce for me

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

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

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.

I really like this checklist idea actually!

Right, but did you really study?

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

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

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

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

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

I appreciate all the advice you've given mate!

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

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

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

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.

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

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

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.

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

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

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

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

Dude runs an NGO lol

He's jewish too I'm weak

@here Anyone know anything about bond valuation ?

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

Also yes

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?

I got 8%

I used this "

I used this as my example to go off of.

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

This is a similar example.

Lemme find my calculator

^uploading

ty

Pretty sure 8 is correct

Would just be the average

Ok good that's what i had thought

What's the other question?

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)

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

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.

Hmm. Send pic of question

2 min

Ok so the equation for AI might be

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

Idk that helps

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.

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

That's usually what semiannual implies.

Ok.

Ty

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

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

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

@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

Good idea

This should work

Halp pls

:)

@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

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

yw!

Anyone able to help with an algebra problem? Pretty basic

@Warren H shoot

9u = 6/5

How do i get to 2/15?

Multiply both sides by 5

so on the left you have 45 u

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

so 45u = 6

then divide both sides by 45

so u = 6/45

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

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

the 3 on top and bottom cross out

so u = 2/15

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

starting from 9u = 6/5

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

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

I'm bad with fractions lol

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)

so u = 6/(5*9)

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

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

cross out a 3 on top and bottom

Ohh okay.

so u = 2/(5*3)

so u = 2/15

yep

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

Yep that will always work

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

-4w = 6/7

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

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

@Warren H the second one

the negative sign stays with the number it is attached to

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

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

Uh. Divide both sides by 9

Oh geez

I didn't see all this

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

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

that means w times a negative number is something positive

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

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

Okay yeah that makes sense.

Ive been working a lot with linear equations

@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!

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

@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?

Yeah I will try to remember that

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 π

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

What's AE?

@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

Although pinging @here works pretty well too

Ah okay. That's good to know @ThisIsChris

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

@Warren H sure!

-2z - 4z = 19+ 4

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

Oh

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

that'll do it

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

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

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

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

Anyone @here to help with another math question?

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

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

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

Is there an equals sign?

No. supposed to solve it

PEMDAS

I meant I knew the answer

Order of operations

Yep did that

Would a photo help for reference?

Yes

Yes.

How do I get 1/24?

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

Simplify 6/9 * 9/144

The 9s cancel out

54/54 = 1 and 1296/54 = 24

And 6 goes into 144 24 times

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

Is that mastering physics but for math

Yes

Or what @micbwilli said

Either works

Okay thanks @GetOffMyState#8267

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

Both rely on what I did above with another example

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

The 9/9 is 1 and can therefore be ignored

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.

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

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

^ this

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

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

Right?

Yes

Because the 9s happen to cancel out

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

You can find the GCD

Okay

Thanks. Yall

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

Multiplication and division are the same really

Same with addition and subtraction

So PEMDAS is easier to remember

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

And same with addition and sibtraction

You might be breaking another rule or your teachers suck. Unless Iβm forgetting something thatβs wrong and you shouldnβt have been marked down

If you are using a computer program it is probably programmed by someone diverse and doesnβt account for multiple but equally valid ways to the answer

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

Yes omg

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

Bring it up in office hours, thatβs BS

And you cant practice the same problem twice

It keeps changing it up
