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.
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.
