Exercise 20. Many
texts give an alternative definition for , starting
with (5-1) as the definition
20 (d). Now use the
Cauchy-Riemann equations to conclude from part (c) that
Solution 20 (d).
See text and/or instructor's solution manual.
Solution. From part (c)
, so that
, , , .
The Cauchy Riemann equations are
Hence we obtain .
