WebOur definition of differentiability should distinguish the fold in the surface from the smooth parts of the surface. To be consistent with the one-variable case, the function should fail to be differentiable along the fold. Given some point , the function is differentiable at the point where if it has a (non-vertical) tangent plane at . Webgeometrically, the function f is differentiable at a if it has a non-vertical tangent at the corresponding point on the graph, that is, at (a,f (a)).
