# Thread: Integration of an analytic function

1. ## Integration of an analytic function

I have an example I want to clearify,

Let C be a semicircle from 2 to -2 which passes through 2i and let T be a semicircle from 2 to -2 which passes through -2i.

If you take the integral of z^2 dz around both paths the is the same as the function is analytic so the integral is independant of the path,

However if you take the integral of the conjugate of z over these to paths you get

So they equal, but the f(z)=conjugate of z isnt an analytic function, is it just a coincidence?

Solved!
