Question attached. Z is a complex variable, z=x+iy help_outlineImage Transcriptionclose1 )2 + ơ-2)2] is harmonic in every region which does not include the point (1,2). (a) Prove that ψ = Inf(x- (b) Find a function ф such that ф + ir is analytic. (c) Express ф+ 3.54. as a function of z. fullscreen
Step 1

To verify the Laplace equation (harmonicity condition ) for the given function and to find its harmonic conjugate

Step 2

A real function V(x,y) is said to be harmonic if V satisfies the Laplace equation: (here subscripts denote partial derivatives)

Vxx+Vyy=0

Step 3

Let us verify that the given fun...
