310 CHAPTER 3. REAL-VALUED FUNCTIONS: DIFFERENTIATION 2. it parametrizes a plane through P = −→ p ( r 0 ,s 0 ) = ( x 0 ,y 0 ,z 0 ) which contains the velocity vector of any curve passing through P in the surface S parametrized by −→ p ; 3. the equation of this plane is −→ N · ( x x 0 ,y y 0 ,z z 0 ) = 0 where −→ N = −→ p ∂r × −→ p ∂s . This plane is the tangent plane to S at P . Let us consider two quick examples. First, we consider the sphere parametrized using spherical coordinates in
