Question

Determine that function is analyte and if so find their derivatives
f(x) =1/2 log(x^2+y^2)+ i tan^-1(y/x)​

Answer 1

Step-by-step explanation:

Let f(z) = y -2xy +i(-x+x2 -y2)+z2 where z = x+iy is a complex variable ... Solution: Our plan is to identify the real and imaginary parts of f, and then check if ... We compute the partial derivatives of u and v as.
