Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am having trouble with this integral, I don't know how to solve it.

integral(x * cos(x))dx

I tried it in the calculator and it gave me the integral back, and I don't know what method of integration to use to figure it out.

Well if anyone has a solution that would be great, thanks.
