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 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 I’m forgetting something that’s wrong and you shouldn’t have been marked down

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

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, that’s BS

And you cant practice the same problem twice

It keeps changing it up

This sounds a lot like mastering physics

Whenever you get it wrong

Yeah haha and I am not a scientific person

I'm majoring in media production.

Bring it up with whoever you can. If you actually understand the concepts you shouldn’t be graded down

I might. My instructor is Asian with a broken accent of course. Yeah I've demonstrated that I understand how to do the concepts

Send screenshots or show photos of your work and really nail them down. Say “show me what’s wrong or the programming is bad”

If you have white TAs or even TAs that speak English use them

What's a TA?

Oh nvm

LOL

Sorry duh

Oh I thought it was joke, haha. You’re good

I got my STEM degree on the west coast so I know a thing or two about Asian “teachers”

This guy isn't even a "teacher" he just sits at his desk while we come into class to work on a $100 computer program

Straight up caught a Chinese born TA giving answers to a Chinese born student before the midterm in office hours

Wow

The educational system is welfare for people that want to pretend they have a job

That’s why it’s occupied by women at the lower levels

That and the fact that it is about nurturing children until about 6th or 7th grade

Yeah pretty much. At the lower level it's not too bad. But after that I can agree. I'm gonna have to see if there's any white TAs around lol

Was there a guy in here offering Calculus help

I may an hero if I have to listen to my 1st Gen immigrant instructor try to explain Calculus concepts without teaching how to solve problems.

@Corey

@Deleted User there are a few of us who can help with calculus. Personally I used to teach it for many years. What kind of problems are you trying to solve?

We started with limits and are moving into derivatives and tangent lines. It just seems like the instructor is getting high on his own supply of math knowledge and not teaching us a clear cut way to solve the problems.

He also doesn’t explain any rule he uses especially with algebraic manipulation which makes it difficult to follow.

I’m having trouble recognizing the problems and what rule to apply to find solutions

read the book along with the class

also, talk to the dept head maybe

Yeah right now I’m fairly reliant on the YouTube.

@Deleted User feel free to regularly post photos of problems you are working on

Sure when I hit a roadblock I’ll post a pic

@Deleted User Professor Leonard on YouTube has great videos for calc concepts. Also feel free to post pictures of problems if you want to.

this Professor Leonard guy is swole af

Does anyone here know Matlab? I’m taking a Matlab class and am super confused

@Sam Southern - TN I know *some* Matlab, what's up?

Driving rn, I’ll send what I’m working on in like 10. It’s basic (apparently lol), but I am not good at the cyber

Gen Z not being good at cyber hahah not living up to my gen I know

@Sam Southern - TN sounds good, post it when you can

1. Write a function (I'm calling it v) that takes in two scalars (a and b) spits out a vector (v) that is a row vector of the length b with the terms being the first a powers of b

So I tried to do someting like this:
function v = hw1_problem5(a,b)
b = length(v);
v = a.^b;
end

so that the function length would track with b and the vector would be that length

and the vector itself would use vector exponent rule of .^ to raise each to the correct power

but it's only giving me the first output instead of all of the outputs

for example, when I input hw1_problem5(2,3), it should output a row vector containing the first 3 powers of 2

so [2 4 8]

but it only gives [2]

so it's not accepting my length argument somehow

there's another one after that that involves zeroing out part of an array in certain locations, but I'll take any help i can get
