For a function in three-dimensional Cartesian coordinate variables, the gradient is the vector field: As the name implies, the gradient is proportional to and points in the direction of the function's most rapid (positive) change. For a vector field written as a 1 × n row vector, also called a tensor field of order 1, the gradient or covariant derivative is the n × n Jacobian matrix: WebThe gradient of f is defined as the unique vector field whose dot product with any vector v at each point x is the directional derivative of f along v. That is, where the right-side hand is the directional derivative and there …

WebWe calculate the magnitude with the Pythagorean theorem, because we can think of a vector as the hypotenuse of a triangle. This is equivalent to using the distance formula, so the magnitude of the vector (a, b) (a,b) is \sqrt {a^2 + b^2} a2 +b2. Let's try an example.
