We’ll start by seeing that every complex analytic function leads to an irrotational, incompressible flow. Then we’ll go backwards and see that all such flows lead to an analytic function.

Then we’ll go backwards and see that all such flows lead to an analytic function. We will learn to call the analytic function the complex potential of the flow.
