Can anyone help me with this pls?(adsbygoogle = window.adsbygoogle || []).push({});

How can you prove that the integral of f(z) around the contour z= 1 is 0

where f(z) is Log(z+5)

Thx

I know Log(z) is ln r + i (theta). But i dont know how that applies to this situation.

Also, do I solve it as a normal integral or use the Cauchy Goursat theorem to prove that its integral is zero?
