I'm studying for my calc final and I'm having a brain burp.

How do I integrate this?

(int) 3x sin(x^2) dx ?

Set the function u = x^2, which means that du = 2x dx

Substitute these terms into the function so you get

3/2 fnInt(sin(u) du)

Integrate that and plug u back in to the function.

AHA!

Thank you. I kept wanting to do u = sin x^2 and I knew that wasn't right.
