[tex]z\in\mathbb C[/tex]
I imagine it is not too difficult, I'm just missing something. I need to use the limit definition to prove it,
[tex] lim_{Δz\rightarrow 0} \frac{f(z+Δz)-f(z)}{Δz} [/tex]
Alternatively, using Cauchy-Riemann conditions, am I correct to assume
[tex]u(x,y) = x^2 + y^2[/tex] and [tex] v(x,y) = 0 [/tex]
Then,
[tex]u_x ≠ v_y[/tex] and [tex]u_y ≠ - v_x[/tex]
?
Thanks!
