Negative Exponent Trigonometric Integrals
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 as sin^- n (x) (or cos), but I'm mostly interested in the exponent - 2.
Thanks in advance to anyone who gives it a shot!
