For the grad-level education I want, I need an understanding of chemistry, physics, and calculus at a minimum. I have a BA in a tangentially related field (or will in a couple months). What are the best resources for learning these subjects without spending even more time/money on tuition? [more inside]

My math skills are no where near where I'd like them to be. Can you recommend a self-paced math learning site? Pretty much any branch of math can apply. [more inside]

I have forgotten basically all of math, and I want to learn it again from the ground up. [more inside]

Attention math teachers: what processes does your college/university use for placement into Calculus courses? [more inside]

I have always had difficulty with mathematics. Now I'm in my mid-thirties and have gone back to school to study engineering. Things are not going appreciably better than they did the first time I went to university. What can I do to fill the gaps I have and become a skilled problem-solver? I want to go from being a C to being an A student. [more inside]

Asking for a friend: With the use of Fourier series, I'm trying to solve an ODE of the form L*y'' + R*y' + y/C = r(x), where r(x) = 1 - x^2 for |x| <= 1, i.e. has a period of 2. To do so I need to represent 1 - x^2 as a Fourier series. In doing so I have to integrate e^(-n * i * pi * x), but I've reached a stumbling block. [more inside]

Applied Math Filter: Help me use math!
I'd like to learn more about mathematics and it's practical applications - particularly in Computer Science [more inside]

Maximal volume of an ellipsoid... [more inside]

Quick help needed for my rusty calculus. Regarding algebraic functions, are the terms "no limit" and "limit does not exist" synonymous?

I remember reading an anecdote about Feynman, written by Feynman either in Surely, You're Joking or What Do You Care What Other People Think. He was describing how in his undergraduate years people were really impressed by his ability to do integrals, all because he knew this integration technique that wasn't taught very often. What was that technique?

I would like to relearn some calculus on my own. Please recommend the best book for the purpose. [more inside]

Can you help me with my innumeracy? [more inside]

Stupid calculus question inside. [more inside]

So I want to be an actuary. My grasp of calculus at present is sketchy. This is a problem. [more inside]
