                           we have
                                                     x P = x M − PM sin α

                                                    y P = y M + PM cos α.                  (8.35)
                           Figures 8.45–8.47 illustrate three stages of this program in operation as applied to
                           the region around an airfoil. More resulting triangulations for domains of various
                           geometries are shown in Figs 8.48–8.53.
