Homework Statement
Verify that each of the following functions is entire:
f(z)=(z^2-2)e^(-x)e^(-iy)
Homework Equations
The Cauchy Riemann equations u(x,y) = ______ and v(x,y) = ______
u_y=-v_x
u_x=v_y
The Attempt at a Solution
So, I've done a few of these problems and understand that to prove it's entire we need to show that the C-R equations exist for all z and are satisfied. Also, noting that Ux Uy Vx Vy are continuous.
My problem is, I'm not sure how to get this into correct form. What is u(x,y) =?
Do I distribute first? How to change this function into something that works?
Would it be
(z^2-2)/(e^x*e^iy)
Is that a good start? :/
