Homework Statement
Homework Equations
Using Cauchy Integration Formula
If function is analytic throughout the contour, then integraton = 0. If function is not analytic at point 'a' inside contour, then integration is 2*3.14*i* fn(a) divide by n!
f(a) is numerator.
The Attempt at a Solution
But book answer is 2*3.14*i. They haven't included the negative sign. I got same error for similar question. They haven't included the negative sign there as well. They've used Laurentz series. Why is my method wrong?
