I have two questions on complex integration, and I do not know how to solve them. Please help if you can.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks

1. Evaluate the following principal value integral using an appropriate contour.

Integration of (integral goes from 0 to infinity) : (x)^a-1/1-x^2,

0<a<1.

2.Using contour integration and calculus of residues, find the sum

Summation (going from 0 to infinity) 1/n^2 +a^2
