Webfor all z with z > 0. We shall see later that Laurent series expansions are unique, and so this must be the Laurent series representation for e1 z. In particular, we know that if C is a simple closed contour about the origin, with positive orientation, then the coefficient of 1 z is b 1 = 1 2πi Z C e1 z dz. Since b 1 = 1, we have Z C e1 z dz ... WebElementary Functions Exp [ z] Series representations. Generalized power series. Expansions at z == z0. For the function itself.
