London Math. The angle α(0 ≤ α ≤ π) between two intersecting curves C1 and C2 is deﬁned to be the angle between their oriented tangents at the intersection point z0. By conformal mapping Q can be represented onto a “canonical” rectangle R = {w = u + iv: 0 < u < a, 0 < v < b} such that the points z 1, z 2, z 3, z 4 correspond to the vertices 0, a, a + ib, ib, respectively. This conformal mapping is important in fluid mechanics because it transforms lines of flow around a circular disk (or cylinder, if we add a third dimension) to straight lines. 666.7 666.7 666.7 666.7 611.1 611.1 444.4 444.4 444.4 444.4 500 500 388.9 388.9 277.8 444.4 611.1 777.8 777.8 777.8 777.8 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Function f(z) = z2 is a conformal mapping from Cf0gonto Cf0g.
