About this document
Understanding Directional Derivatives and Gradients by maja is a document available to read on EtoBox.
1. The document discusses directional derivatives and the gradient in R2. It is shown that the formula for calculating the directional derivative from partial derivatives only holds for continuously differentiable functions. 2. The gradient of a function f, denoted ∇f, is defined as a vector of the partial derivatives of f. For continuously differentiable functions, the directional derivative in direction ha,bi at a point is given by the dot product of the gradient and ha,bi at that point. 3. Examples are
