If $C$ is a counterclockwise path in the $z$-plane such that $\mid z+1 \mid =1$, the value of $\dfrac{1}{2 \pi \: j} \oint_c f(z) dz$ is $-2$ $-1$ $1$ $2$ Complex Variables gate2012-ee complex-variables cauchys-integral-theorem + – Andrijana3306 asked Mar 23, 2018 • recategorized Mar 7, 2021 by Lakshman Bhaiya Andrijana3306 1.4k points answer comment Share See all 0 reply Please log in or register to add a comment.
