How do I evaluate the integral [math]\int\log x\sin x\,dx[/math]?
I see. But how do we evaluate [math]\int\frac{\cos x}{x}\,dx[/math]?
That's a good question. Unfortunately, there is no elementary antiderivative for that function, so we need to use other techniques, such as numerical or approximation methods. Would you like me to recommend any?
