In curvilinear coordinates, or more generally on a curved manifold, the gradient involves Christoffel symbols: ∇ f = g j k ( ∂ f i ∂ x j + Γ i j l f l ) e i ⊗ e k , {\displaystyle \nabla \mathbf {f} =g^{jk}\left({\frac {\partial f^{i}}{\partial x^{j}}}+{\Gamma ^{i}}_{jl}f^{l}\right)\mathbf {e} _{i}\otimes \mathbf {e} _{k},} See more In vector calculus, the gradient of a scalar-valued differentiable function $${\displaystyle f}$$ of several variables is the vector field (or vector-valued function) $${\displaystyle \nabla f}$$ whose value at a point See more The gradient of a function $${\displaystyle f}$$ at point $${\displaystyle a}$$ is usually written as $${\displaystyle \nabla f(a)}$$. It may also be denoted by any of the following: • $${\displaystyle {\vec {\nabla }}f(a)}$$ : to emphasize the … See more Relationship with total derivative The gradient is closely related to the total derivative (total differential) $${\displaystyle df}$$: they are transpose (dual) to each other. Using the … See more Jacobian The Jacobian matrix is the generalization of the gradient for vector-valued functions of several variables and See more Consider a room where the temperature is given by a scalar field, T, so at each point (x, y, z) the temperature is T(x, y, z), independent of time. At each point in the room, the gradient of T at that point will show the direction in which the temperature rises … See more The gradient (or gradient vector field) of a scalar function f(x1, x2, x3, …, xn) is denoted ∇f or ∇→f where ∇ (nabla) denotes the vector differential operator, del. The notation grad f is also commonly used to represent the gradient. The gradient of f is defined as the … See more Level sets A level surface, or isosurface, is the set of all points where some function has a given value.
