The interest earned on a bank account, the arrangement of seeds in a sunflower, and the shape of the Gateway Arch in St. Louis are all intimately connected with the mysterious number e. In this informal and engaging history, Eli Maor portrays the curious characters and the elegant mathematics that lie behind the number. Designed for a reader with only a modest mathematical background, this biography brings out the central importance of e to mathematics and illuminates a golden era in the age of science.Thus, vertical lines x = const. of the z-plane are mapped onto circles R = e^ = const. concentric about the origin of the w-plane, while horizontal ... We use the formula for the arc length of a curve given in polar form as r = f(6): 6, S J ra + (#) d6.
