Not exactly sure how it is at A&M. I mean, Greek life has gotten a lot bigger down here but I really don't know too much about it. I'll probably ask my friend about how it is at Arkansas because Greek life runs that school and it would probably help me learn a bit more.
It's easier to show with examples, but it basically makes more complex integrals easier to integrate by swapping u in for one of the parts.
So, say you're trying to find the integral of x*(cos x^2 + 1)dx. You could set u = x^2 + 1, which would mean du = 2x dx. So now you're looking for the integral of 1/2 * cos u du. Much easier to integrate.
It takes practice to know what to substitute at times but the idea is to make the integral easier.

id like to get ahead of my calc class
I joined a fraternity and I love it.
go for it
