## Homework Statement

find integral of the function- (x^2 + cos^2)(cosec^2) / (1+x^2)

**2. The attempt at a solution**

I noticed the denominator is the derivative of Arctan(x), I tried integrating by parts with various choices for 1st and second function but all of them end up being more complicated, I tried factoring in sec^2(x) which also didn't go a long way. I would appreciate some help to proceed further with this integral
