Differential Geometry question

I am looking for a rigorous proof of the following theorem (which I qoute from Schaum Differential Geometry book):

"If $\displaystyle K\ne0$ at a point P on a surface, show that there is a neighborhood of P in which the points can be put into a 1-1 correspondence with the spherical image of the neighborhood (see Problem 9.57)".

Note: K is Gauss curvature.
