Hi I got a question, which I think may be a trick question.
"State Cauchy Riemann equations for real valued functions u(x,y), v(x,y).
we know a function is generally of the form
f(z) = u(x,y) + iv(x,y).
but U is the real part and V is the imaginary. so why does the question say "state the CRE for REAL VALUED FUNCTIONS u(x,y), v(x,y)."
