Evaluate

What I tried so far is to break the denominator as (1+Cos2x). The integral of 1/(x^2+2) can be done with substituting x = sqrt(2)u and will evaluate to a constant times arctan (x/sqrt(2)) but I have no idea how to evaluate the rest. This is calculus AP (with real numbers only). My daughter asked me about this problem and I am stuck :). Any help is much appreciated.
