Hello guys, just finish learning about Derivatives and Limits yesterday, so I thought I could get started on Integration now.

I've looked in alot of places but can't find out how to integrade a multiplication/division! I mean, addition and subtraction are easy stuff, just distribute the integral sign but how are multiplication, division handled?

Here:

Integrate: 3x(Cos(x^3 + 7))

Integrate: (x+1)/(x-1)

Thanks for any help!
