Why is the gradient perpendicular to the tangent of a plane?

Weband means that the gradient of f is perpendicular to any vector (~x−~x0) in the plane. It is one of the most important statements in multivariable calculus. since it provides a crucial link between calculus and geometry. The just mentioned gradient theorem is also useful. We can immediately compute tangent planes and tangent lines: WebFor the planar curve, we can give the curvature a sign by defining the normal vector such that form a right-handed screw, where as shown in Fig. 2.5. The point where the curvature changes sign is called an inflection point (see also Fig. 8.3 ).
