The correct answer to this derivative is 3/2(sqrt3x+4). I just don’t know where in the work I was supposed to multiply by three or how that works into the equation. Thanks for the help in advance!

I know how to find discontinuities and domain, it is the exponents that are tripping me up

Recently (over the past year), I feel like I've been overly reliant on AI for homework. I gaslit myself into thinking I was using it "responsibly" (using learning mode, telling it only to give vague hints, etc.), but I feel like that had a negative effect on my problem-solving skills. Because of this, I decided to stop using AI this semester to see if it would help.

Now I feel helpless when working through problems, especially in pure math. If you're in a similar position, please stop using AI. Even though it gives vague hints, those hints are usually the difference between figuring it out yourself and not.

My motivation has gone way down since everything is much harder and I procrastinate more. What should I do when I hit a wall where I’d normally turn to AI? Does this get better with time after solving more problems, and is pushing through it actually worth it?

I'm not sure if the question is wrong, or if I'm going crazy, this is the second time this semester in this class that this has happened. Surely I'm not THIS bad at math. Anyone else getting the "right" answer??

Unsure of where I went wrong on exercise 2

Idk if this is allowed here..Its straight forward "determine the resultant force acting on the hook in cartesian notation", I dont know if its my angles or if I am skipping a step but 490, 117, -266 sure aint it (per person's mastering) can anyone see and point out where I went wrong? Maybe I'm not doing my computing right or ive set up wrong. Ive been on this problem for 1.5 hours.. i dont know why. This is an online class so all I have is a textbook and dr Hanson videos, which are helpful so im confused on why im struggling so much? All im looking for is a point in the right direction. For now ill move onto the next problem but it is just the same so may post it as well 😅

I genuinely have no idea how to solve these. Only thing I know is that we can't directly sub in zero since that leads to an indeterminate answer.

I'm stuck on part B of this problem and would love any insights that could help point me in the right direction. I know that I should be using the law of total probability, which from my understanding (I double checked with my textbook) allows me to just add all of the intersections of the conditional probabilities however when you add them (.5+.4+.6) you get a number greater than one which can't be the answer as probabilities are between 0 and 1. It feels to me like I'm missing something obvious but I can't put my finger on it. Any help is much appreciated!

I am given a bunch of functions and their fourier series, with the constant not filled in. I'm supposed to find the constant coefficient a0 without Euler's formulas. I'm not sure how to approach such a problem.

An example of such a function and series:

f(x) = x*(pi² - x² )

f*(x) = a0 + 12 * ( sin(x)/(1³ ) - sin(2x)/(2³ ) + sin(3x)/(3³ ) - ...

EDFINITY FUCKING SUUUUUUUUUUUUUUUUUUUUUUUUCKS

sorry, just pissed.

so I just renewed my account (cost like 60 bucks too) and now im trying to join my professor's class, and whenever i click the registration link, or try to join it prompts me to pay AGAIN. I ALREADY PAID. I cannot get into contact with edfinity because for SOME GODFORSAKEN REASON THE CONTACT US LINK IS JUST FUCKING BROKEN. The help center also doesn't have any info on this, has anyone else experienced this issue? I'm going to scream.

guys I just want to do my fucking calculus.

(also sorry if this isn't the best sub for this, I don't know what is, I just saw someone else had posted a question about the hell homework site here.)

I need to create a presentation on a statistics/biostatistics related topic for my statistical core group and I have no idea what to present on. It's in a couple months.

I don't want to present a method because the audience is mixed with junior and senior statisticians who may know more than me on the topic.

Some past presentations this year have been on integrating AI into coding, linking SAS and R code, and how AI can be used to do literature reviews and estimate historical statistics. As you can see, these topics are very general and provide information that anyone can use while also being niche enough that some people may not know about them. They're also topics that don't require a great depth of knowledge to be presented on.

The presentation has to be about a half hour long so it has to be general but useful. It's hard to pull from projects I've worked on this year because I've learned new methods but they aren't interesting and again, some people may know as much or more about them than I and I don't have the time or confidence to become an expert within a couple months in the method to field questions from our core's senior members.

TIA for any suggestions on topics or even resources I can look to to find ideas for topics!

Instuctor prompts were not included, but any methods are allowed. Can someone please help me understand this?

Please help

I found that AMn=aP/2^n but I can't find P in terms of n. I have P * 1 = 1 and P * 2 = 3 and P * 3 = 5 and P * 4 = 11 because AM * 1 = a / 2 and AM * 2 = 3a / 4 and AM * 3 = 5a / 8 and AM * 4 = 11a / 16

I know how to do row reduction, but my attempts are producing completely different flop counts.

I worked this out and got -1/8, the answer was wrong and I'm not sure where the math went wrong. Everyone I talked to said the same. Anyone care to weigh in?

College level microbiology. Can someone please explain this to me like I'm 4. Please and thank you.

Someone helped solve the problem but they didn’t explain how they got the answer, could someone help me?

I know how to complete the square but I'm baffled where the u-sub came from. I did u = x - 1/2 instead.
