Sep 5, 2019 · I am having trouble understanding visually what a gradient is. My understanding is it is a generalisation of tangential slopes to higher dimensions and gives the direction of steepest ascent. …

May 10, 2020 · 3 I was studying Multi-variable Calculus, and I got confused with the definition of the Gradient. The definition that I learned was this: But, doing some examples, and searching in Google I …

Mar 11, 2015 · 0 Gradient simply means 'slope', and you can think of the derivative as the 'slope formula of the tangent line'. So yes, gradient is a derivative with respect to some variable. In vector analysis, …

Feb 18, 2015 · The $\nabla \nabla$ here is not a Laplacian (divergence of gradient of one or several scalars) or a Hessian (second derivatives of a scalar), it is the gradient of the divergence. That is why …

Feb 14, 2022 · The "gradient" is the vector representation of the linear transformation in this approximation. There are some geometrical motivations that makes the gradient to be thought as a …

A gradient is a vector, and slope is a scalar. Gradients really become meaningful in multivarible functions, where the gradient is a vector of partial derivatives.

1 The gradient points to the direction of faster growing of the function. See The Gradient and Directional Derivative.

Oct 28, 2012 · The gradient is most often defined for scalar fields, but the same idea exists for vector fields - it's called the Jacobian. Taking the gradient of a vector valued function is a perfectly sensible …

Sep 17, 2013 · It bears mentioning that the second formula works for any combination of dimensions, while the first works only when a, b a, b are 3 3 -vectors and you are taking the gradient with respect …

Could anyone explain in simple words (and maybe with an example) what the difference between the gradient and the Jacobian is? The gradient is a vector with the partial derivatives, right?
