Partial derivative — In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary).… … Wikipedia
partial derivative — Math. the derivative of a function with respect to one of its variables with all other variables held constant. [1970 75] * * * In differential calculus, the derivative of a function of several variables with respect to change in just one of its… … Universalium
Derivative (generalizations) — Derivative is a fundamental construction of differential calculus and admits many possible generalizations within the fields of mathematical analysis, combinatorics, algebra, and geometry. Derivatives in analysis In real, complex, and functional… … Wikipedia
Second partial derivative test — In mathematics, the second partial derivatives test is a method in multivariable calculus used to determine if a critical point ( x , y ) is a minimum, maximum or saddle point.Suppose that :M = f {xx}(a,b)f {yy}(a,b) left( f {xy}(a,b) ight)^2 or… … Wikipedia

Functional derivative — In mathematics and theoretical physics, the functional derivative is a generalization of the directional derivative. The difference is that the latter differentiates in the direction of a vector, while the former differentiates in the direction… … Wikipedia
Covariant derivative — In mathematics, the covariant derivative is a way of specifying a derivative along tangent vectors of a manifold. Alternatively, the covariant derivative is a way of introducing and working with a connection on a manifold by means of a… … Wikipedia
Second derivative test — In calculus, a branch of mathematics, the second derivative test is a criterion often useful for determining whether a given stationary point of a function is a local maximum or a local minimum.The test states: If the function f is twice… … Wikipedia
