So, the tangent plane to the surface given by f (x,y,z) = k f ( x, y, z) = k at (x0,y0,z0) ( x 0, y 0, z 0) has the equation, This is a much more general form of the equation of a tangent plane than the one that we derived in the previous section.

WebWe already know that this formula is true for w = z0 and f(z) = 1 (example). If f is a polynomial, one can write it as f(z) = f(w) + (z w)g(z), where g is holomorphic and use the same method to prove it. A similar idea works for a general f. Theorem.
