2 Complex Functions and the Cauchy-Riemann Equations
www.math.columbia.edui are complex numbers, and it de nes a function in the usual way. It is easy to see that the real and imaginary parts of a polynomial P(z) are polynomials in xand y. For example, P(z) = (1 + i)z2 3iz= (x2 y2 2xy+ 3y) + (x2 y2 + 2xy 3x)i; and the real and imaginary parts of …
