Thread: complex variable

I every one.
I am trying to solve the following:
integral of (z^2+2) from 0 to infinity in complex ?

Cauchy-Riemann equations show that your function is analytic. So you can just integrate it on the real line which makes it just a real numbers integral.

What is the integral if (x^2 + 2) from 0 to infinity?

Infinity.

= inf
