This figure shows a diagram of the complex plane with the axes unlabelled concentrated in the upper-right quadrant. The following points are labelled; 2, 2 plus i and i. A path labelled capital gamma is labelled and consists of three joining line segments. The first from zero to 2 with an arrow marked in that direction, from 2 to 2 plus i again with an arrow and from 2 plus i to i with another arrow.
