Hi, this is fairly fundamental and basic, but I cannot seem to make sense of it(adsbygoogle = window.adsbygoogle || []).push({});

I know z = x + iy

and hence a function of this variable would be in the form h = f(z). BUT I do not understand why

f(z) = u(x,y) + iv(x,y)

why so? in z = x + iy, x is the real part and iy is the imaginary part, so why does y have influence in real part and x have influence in the imaginary part in f(z)?

Thanks

Thomas
