Homework Statement
f(z) = u(x, y) + iv(x, y)
where z ≡ x + iy. Let the fluid velocity be V = ∇u. If f(z) is analytic, show that
df/dz = V_x − iV_y
Homework Equations
V_x = du/dx
V_y = idu/dy
The CR equations du/dx = dv/dy, du/dy = -dv/dx.
The Attempt at a Solution
I attempted to use this form for d/dz: d/dz = d/dx - i*d/dy.
This gave me df/dz = 2(V_x - iV_y) though.
