Hey,(adsbygoogle = window.adsbygoogle || []).push({});

I've been trying to do this integral without cauchy's theorem (with the theorem i get 6ipi in like 2 steps). Im stuck at this point, I have found afew ways to do the integral im stuck on but they all involve multiple variable changes and I was wondering if there is a simple way to do this that i'm not seeing.

sorry typo, its not supposed to be 1/2 ln(1+2e^(it)) just ln(1+2e^(it))

Thanks in advanced
