Title: Chapter 1.6 Question 9(b)
Post by: Justin Cheung on October 21, 2018, 12:22:07 AM
Does anyone know what Question 9(b) from Section 1.6 is asking us to do ? I have read the question a few times and I still do not seem to get the hang of it.

The conclusion of Example 13 is
\frac{1}{2\pi i}\int_\gamma \frax{dz}{z-p}=\left\{\begin{aligned} &0 & p\text{ outside }\gamma\\ &1 & p\text{ inside }\gamma. \end{aligned}\right.
You are asked to verify it for $\gamma$ specified in 9(b) using two decompositions in 9(b)
