Hi everyone,
I am doing a complex variable course and I am a bit stuck on a certain problem involving branch cuts. I can't seem to find a good intuitive explanation anywhere online and my calculus books don't even mention them.
Anyone know of a good online resource for this, or even your own explanation? For example, how would you use branch cuts to solve the following integral:
int_0^inf (log(x))^2/(1+x^2) dx
Any help appreciated. thanks
