Derivative of scalar product
Webfor all vectors u.The above dot product yields a scalar, and if u is a unit vector gives the directional derivative of f at v, in the u direction.. Properties: If () = + then = (+); If () = then = + (); If () = (()) then = ; Derivatives of vector valued functions of vectors. Let f(v) be a vector valued function of the vector v.Then the derivative of f(v) with respect to v (or at v) is the ... WebThe covariant derivative is a generalization of the directional derivative from vector calculus. As with the directional derivative, the covariant derivative is a rule, , which takes as its inputs: (1) a vector, u, defined at a point P, and (2) a vector field v defined in a neighborhood of P. [7] The output is the vector , also at the point P.
