I've run into a couple of integrals I didn't know how to solve. I managed to find the solution to only one of them (INTEGRAL 1/sin x =- ln |csc x + cot x| + C)

I'd like help with the following, (kind of urgent - doing some tutoring and need to clear up stuff like this in case it comes up):

1.INTEGRAL 1/sin^2 (x)2.

INTEGRAL 1/cos^2 (x)

I'm guessing the solutions for both are similar..and I'm assuming there may be a formula for integrals such assin^- n (x)(orcos), but I'm mostly interested in the exponent- 2.

Thanks in advance to anyone who gives it a shot!
