WebAug 14, 2024 · Example 2.1. 1. The function w = z 2 is a single-valued function of z. On the other hand, if w = z 1 2 , then to each value of z there are two values of w. Hence, the function. w = z 1 2. is a multiple-valued (in this case two-valued) function of z. Suppose that w = u + i v is the value of a function f at z = x + i y, so that.
