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 forREAL VALUED FUNCTIONSu(x,y),v(x,y)."
