Stuck on trying to integrate
(4 + 3sec(2x))^2
If we expand it out, we get:
Now, integrate term by term and it ain't bad.
Problem is I don't know the integral of 24sec(2x) I know sec^2(x) becomes tan(x). Thats where I was getting stuck, I put the full equation out so that I could check if I had expanded correctly.
