    you can use eulers theorem to solve this e^(ix) = cos(x) + i *sin(x) .. then solve and take the real part.. or you can also use IBP twice to solve this ...

    We didn't learn Euler's theorem, only IBP, but I couldn't get the answer

    What do you mean by analytically? Can't you do Integration by parts?
