My integration skill is very poor, there a many integral that I can't solve, for example:
$$\int_{0}^{\infty}\frac{\sin^{2n+1} x}{x} dx$$
$$\int_{0}^{\infty}\frac{\cos ax-\cos bx}{x} dx$$
but my friend could solve them very quickly, so may I wonder if there are any books about technique for proper and improper riemann integral? Also what is the best way to master integration?
$$\int_{0}^{\infty}\frac{\sin^{2n+1} x}{x} dx$$
