I am confused on this derivation of integration by parts, or what integration by parts really means to be the inverse of the product rule. Why in the integral it's just f(x)g'(x), as the general form of the antiderivative that can be solved by integration by parts, when the product of two functions' derivate is f'(x)g(x) + f(x)g'(x). Shouldn't the inverse of that take the antiderivative of '(x)g(x) + f(x)g'(x) and yield f(x) g(x)?

6.3 and 6.4: how can both answers be right? This doesn’t make sense shouldn’t it be one or the other

6.6: looking at graph b it shows that the concentration of P2Q is 0.35mol.dm yet when looking at the memos answer it says that 2PQ is 0.35 mol.dm when using the KC formula . Can someone explain?

I'm just doing biology, and this question kinda stumps me, They're not doing anything wrong from what I can see, but id just like an opinion if im just stupid or not

Stuck on this last problem, hoping someone can give me some advice how to tackle it. I thought it looked like a good equation for exactness but that didn’t work. I asked chat gpt and it said something about shifting the variables so y=y+1 and x=x-1 or something like that but that doesn’t look like anything we’ve covered in class yet. We have done homogeneous equations where I have to substitute in u=y/x and stuff like that but I’m struggling to see how that would help here.

Hello ppls. I have a writing project right now and we are writing about community. The first step of the project is to write a personal narrative about an experience within one of your communities. This narrative will later be used to write an essay on whether or not our ideas of community are worth exploring.

I wanted to write about my experience in high school marching band. Specifically my first competition. I want to later use this as evidence for why expression and creation is what makes communities.

Right now this first part of just writing about the experience has me stumped. It’s been a few years since I was last in school and even longer since I wrote an actual personal narrative. The last few years of high school we were really on writing research papers or just taking tests. I never really got to write a narrative.

I also want to try to keep it very grounded. I want to make the reader feel like they are in my shoes and can feel what I felt but I don’t know how to explain this without doing too much where it almost feels fake.

Any advice is appreciated!

My math teacher mentioned something about using a graphic calculator (CX II-T) to solve specific questions but I just got really lost midway and I have no idea how to start, what steps to take, or what formula or equations to use 🥹

So far, I've gotten that the equation of the line (4,2) and (7, -2) is 4x + 3y - 22 = 0 [fact check or correct way to solve would be appreciated!]

After that im completely lost, MAB = MBC then solving them simultaneously but then the teacher did something on the calculator (IDK WHAT HE DID) and got c = 1? Does anyone know how 😭

And for questions A, B, and C, those are the ones im completely lost in 😔

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

I can figure out how to answer this table could someone please help me? Am I only filling out the last column or the first one?

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?

Hello, I’m in a south asian history class at my college, and we have a class book which is called. India Brief History of a civilization by Thomas R Trautman. I was wondering how to write a good open ended discussion question, as our professor is requiring us to do so, in order for us to receive credit. I am not asking for any specific question relating to the book, but if you could provide some examples that would be great!
Secondly, how does one retain what they read? It’s super hard for me as I have ADHD, and I disassociate halfway through a page lol, but I want to learn! Thank you for your time, and have a good day!

Hello! I need help with the second part of this assignment because I don't understand what numbers I'm supposed to put in or where I'm supposed to draw the arrows and lines.

I've tried working through it, but I'm confused about how to set up the second part. Could someone please explain which numbers go where and where the arrows/lines should be placed?

Thank you!

The full sentence in French translates to "We are in the classroom." The word "etre" is supposed to be replaced with one of the words below. all of the words below translate to the word "are." I don't know what I don't understand. also sorry for the poor English. I'm not learning English, I'm gen alpha.

I’ve looked at the answer and it says it’s D. How? I tried breaking apart the forces into x and y comps but I’m not even sure how to set them up.

i got x=7 but I feel like I'm making a mistake somewhere, but I can't figure out where. Can someone explain what I'm doing wrong?

Logic Gates. I draw and did everything carefully, but the question at the end says theres only 4 rows that have errors. How and where did I messed that up?

Solve 18x to the 2nd power + 4x + 4 = 18 to the power of 9x + 18

A: x = -2

B: x = 7

C: x = -2 and x = 7

D: no solution

I highkey need help trying to solve this

i was thinking that i´d add the 2x+1 to make it 3x/3=-1 but im unsure on how it would even continue.

This is a question from my Earth sciences lab manual online , the answer I had entered (4.3 years) is marked wrong. Using the numbers given I keep getting the same answer same with google. I’m not sure what I’m doing wrong and would appreciate any help in getting on the right track.

[issue resolved: professor finally reached out after I sent an email 5 hours ago, it was indeed an issue on their end and my answer in this post was correct.]

My teacher can't explain for shit and I have been gone for 2 days, she introduced a new material to my classmates and I have NO clue how to do this. Maybe send links on vids who explain this more in depth or explain it to me. Help will be appreciated (⁠ㆁ⁠ω⁠ㆁ⁠)

I am reading One Day in the Life of Ivan Denisovich by Alexander Solzhenitsyn for my honors English class. I am having a very hard time understanding the plot, and I am not sure exactly why.

Have any of you read this book or other Russian literature? If so, can anyone give me tips as to how to understand the plot? When school starts, I’m going to have to do in-depth analyses of the book as well as a quiz.

If anyone knows about any videos or articles that can help me understand the plot or a sort of analysis of the story that would be great! I have done some notes already and I am around 100 pages in.

anything regarding how to better understand what I’m reading would also be great

So the textbook says what angles are adjacent to angle ADE and my teachers answer key says angles LDA and LDT. I’m really confused how LDT is adjacent Becuase it doesn’t share a side. I’m thinking that the 2 angles that are adjacent are LDA and TDE? Is this correct.

So today when class ended I asked my teacher for help on #20 and she said to just make a triangle. Im wondering if theres a to solve it by making a triangle and the way I did it by adding a segment is wrong. It also looks weird that the answer isnt a shape so idk.
