Completion requirements

This figure is in two parts: (a) and (b). Each part is a copy of the unlabelled complex plane concentrated in the upper-right quadrant and showing contours labelled capital gamma made up of two line segments. Part (a) has the first line segment from zero to the unlabelled point i with a direction arrow marked and the second from the unlabelled point i to the labelled point 1 plus i. Part (b) has the first line segment from zero to the unlabelled point 1 and marked with a direction arrow and the second from the unlabelled point 1 to the labelled point 1 plus i.
