(a)Show that the function u=x^2+y is not a harmonic function.

(b)show the function v=x+2y is part of harmonic conjugate and say what f(z) is.

Any help?!?!:/

is not (du)^2/(dx)^2+(dv)^2/(dy)^2?!?!

in the next one that I have to do is this:

v=x+2y

dv/dx=1

du/dx=dv/dx so u=x+f(y)

dv/dy=2

du/dy=dv/dy so u=2y+f(x)

So v=x+2y

f(z)=x+2y+i(x+2y)
