Gradient - Wikipedia
WebBiologic Gradient Biologic gradient refers to the presence of a mono-tone (unidirectional) dose–response curve. We often expect such a monotonic relation to exist. For exam-ple, more smoking means more carcinogen exposure and more tissue damage, hence more carcinogenesis. Such an expectation is not always present, however. trips rhyme
Gradient definition - explanation and examples - Cuemath
The gradient of a function is called a gradient field. A (continuous) gradient field is always a conservative vector field : its line integral along any path depends only on the endpoints of the path, and can be evaluated by the gradient theorem (the fundamental theorem of calculus for line integrals). 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 (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 … 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 convention that vectors in $${\displaystyle \mathbb {R} ^{n}}$$ are represented by 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 … 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 Level sets A level surface, or isosurface, is the set of all points where some function has a given value. See more Jacobian The Jacobian matrix is the generalization of the gradient for vector-valued functions of several variables and differentiable maps between See more WebJan 14, 2024 · The concentration gradient refers to the difference of ion concentration inside the cell compared to outside the cell.
