Integrate sinx+2x with respect to x

Use the half angle formula, sin^2 (x) = 1/2 * (1 - cos (2x)) and substitute into the integral so it becomes 1/2 times the integral of (1 - cos (2x)) dx. Set u = 2x and du = 2dx to perform u substitution on the integral. Since dx = du/2, the result is 1/4 times the integral of (1 - cos (u)
