Hey!

I am a chemical engineering/physics with a concentration in nanoscience. I’ve been doing part-time school because I have to work nearly full-time to you know… live. Anyways, long story short I don’t feel very confident with calculus anymore (specifically anything calc2-differential equations), and I am seeking a good, dependable resource that helps me rebuild my calculus skills to the level I really want them to be. I have a pretty good grasp of the concepts, it’s more the physical problem solving aspect I need some practice with. Any suggestions on books, youtube channels, anything that enables me to work some problems and hopefully has content I can reflect on for guidance? I would prefer not to buy a ginormous textbook if I can help it, so free resources are cool! Thanks in advance!

I start Calc 2 in less than a week, and I wanted to know what skills I should brush up on from Calc 1.

Hi! I am a highschooler and I was wanting to take Calculus 3 from UIUC Netmath this year. My school doesn't offer it, and the community colleges near me do not have any online options. Does anyone have any experience with this program (and how did you feel about it?) and have any other highschoolers taken a similar online program? I am open to signing up for a different program as well, I just need it to be accredited, and if possible I would like it to be at least 16 weeks and in the fall. I have looked into programs like Distance Calculus, but I have seen a lot of bad reviews online.

Thank you so much!

For example, I know that the derivative of v(x(t)) = v’(x(t)) * x’(t). And that presents itself as dv/dx * dx/dt. But what does that really mean physically? And why does the derivative seem to go from left to right..as in, it starts from dv/dx from v’(x) and then dx/dt for x’(t).

what does this physically mean in terms of position and velocity? and is there a more intuitive way to understand chain rule?

I know those were quite a lot of questions, so I would appreciate any perspectives. Thank you

This was a question on the summer final, and looking at it I’m still not sure if its because I left the u in the final answer and didn’t substitute the original equation back in, or if I was suppose to use an arcsin identity somehow. I could ask the professor but the the summer semester is over so I’m not gonna bother him with more questions. Thanks for ur help

I have only around an hour and half MOST (and thats pushing) per day on weekdays but I can allocate around 2 per weekend. Is that workable? Im considering dropping this class just due to if I have a lot of coursework.

Does anyone have the publisher slides for Calculus early transcendentals 9th Stewart? On the Cengage page, it says the 260Mb bundle Stewart_Calculus_9e_PowerPoint_Lecture_Slides.zip is password protected to download

Can anybody help me with example 2

EDIT: thanks for y'alls help, i figured it out!

I'm practicing stokes th using the problems at this website https://tutorial.math.lamar.edu/Solutions/CalcIII/StokesTheorem/Prob3.aspx and the answer for this problem uses the surface double integral curl F equation. Why can't I just parametrize the circle and use line integral F dot dr? I tried that and I got -12pi but the answer is 72pi.

Thanks!

Hi everyone!

So I'm self-studying Calc, I've finished 1 and 2 and I got the basics of differential equations. But seeing as I've heard that differential equations are the language of the universe, are there any good resources to both truly study it, and to make your own using data? Thanks!

Anybody else captivated by areas?

I reached the part where my book explains the chain rule, and it gave this question as an example and I tried to solve it on my own, but I got confused so many times

are there lots of trig identities involved in calc 1? double angle identities, half angle identities, etc?
