Elementary Functions of a Complex Variable

Part of the Library of Mathematics book series (LIMA)

Abstract

In the preceding chapters we studied complex numbers from an algebraical point of view, coupled with geometrical interpretations, and this enabled us to arrive at a sensible and consistent definition of powers z r , where r is an integer. We also discussed fractional powers and their many-valuedness. Thus we are in the position to handle expressions like (z1/2 +2z-5)/(3z 2 + i), in which several such powers are combined.
