WebThe #1 Pokemon Proponent. Think of ( d²y)/ (dx²) as d/dx [ dy/dx ]. What we are doing here is: taking the derivative of the derivative of y with respect to x, which is why it is called the second derivative of y with respect to x. For example, let's say we wanted to find the second derivative of y (x) = x² - 4x + 4. WebHence, the directional derivative is the dot product of the gradient and the vector u. Note that if u is a unit vector in the x direction, u=<1,0,0>, then the directional derivative is simply the partial derivative with respect to x. For a general direction, the directional derivative is a combination of the all three partial derivatives. Example

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.
