Hi guys,

I got to solve this integral in a recent test, and literally I had no idea of where to start.

I thought about substituting ##tan(\frac{x}{2})=t## in order to apply trigonometry parametric equations, integrating by parts, substituting, but I always found out I was just running in a circle.

I have even tried to plot the function in an integral solver, but no antiderivative was found.

How's that?
