Chapter 11. Show that the mapping
maps the upper half plane onto the upper half plane plus an infinite rectangle in quadrants three and four.
The Schwarz-Christoffel formula for is:

Integrate to obtain:

This is one, formula for the integral. However, we will use the following form of the integral to continue the computations.

The coefficients are , and we obtain

A graph for the solution is:

Fluid flow over an infinitely deep ditch.
