Question

if -3+ixy and x+y+4i are conjugate to each other , find the value of x and y

Answer 1

Answer:

functions of n variables (n≤2) that are continuous over some domain together with their partial derivatives of the first and second orders and that satisfy Laplace’s differential equation in this domain:

. For example, x2 − y2 and 2 xy, being the real and imaginary parts of the function ξ2 = x2 − y2 + 2 ixy, are harmonic functions.
