About this document

Directional Derivatives and Gradients by Motseilekgoa is a document available to read on EtoBox.

1) The directional derivative of a function f at a point P in the direction of a unit vector u is given by the gradient of f dot product with u. 2) The gradient of a function f is the vector of its partial derivatives and gives the maximum rate of change of f. 3) The tangent plane to a level surface f(x,y,z)=c at a point P is the plane passing through P with normal vector given by the gradient of f at P.
