# Convergence of Integral

## Homework Statement

State whether the problem is convergent or divergent and if its convergent solve the integral. Integral from 0 to inf of (sinx)/(1+cos^2(x))dx

## Homework Equations

there isnt really an equation for this, I dont think.

## The Attempt at a Solution

Im not really sure how to even start this problem. I know it converges, and I know the answer is pi/4 (the book has the answer) but I am stuck on how to figure out that it A) converges and B) how to solve it.

*I know there are several tests you can use to test for convergence (ratio test, p test, etc.) but im not sure which one applies here.
