Hi i'm stuck on a problem and was wondering if anyone could help. The problem is as follows:
"It is required to evaluate
,
using contour integration.
a) consider the function
(You are given that, with , the only branch cut needed is the section [-1,1] of the real axis)
i)Find the value of around a circle of large radius.
ii)Relate M to the value of around the cut.
iii)Express N in terms of L, and hence evaluate L."
Thanks for reading.
