NettetIntegration, the process of computing an integral, is one of the two fundamental operations of calculus, [a] the other being differentiation. Integration started as a method to solve problems in mathematics and physics, such as finding the area under a curve, or determining displacement from velocity. NettetFind the derivative of an integral: d d x ∫ π 2 x 3 cos ( t) d t. Substitute u for x 3: d d x ∫ π 2 u cos ( t) d t. We’ll use the chain rule to find the derivative, because we want to transform the integral into a form that works with the second fundamental theorem of calculus: d d u ( ∫ π 2 u cos ( t) d t) × d u d x.

NettetIf the functional derivative. δF[ϕ] δϕα(x) exists (wrt. to a certain choice of boundary conditions), it obeys infinitesimally. δF : = F[ϕ + δϕ] − F[ϕ] = ∫Mdx∑ α ∈ J δF[ϕ] … NettetA time derivative is a derivative of a function with respect to time, usually interpreted as the rate of change of the value of the function. [1] The variable denoting time is usually written as . Notation [ edit] A variety of notations are used to denote the time derivative. In addition to the normal ( Leibniz's) notation,
NettetAn indefinite integral of a function f(x) is also known as the antiderivative of f. A function F is an antiderivative of f on an interval I, if F'(x) = f(x) for all x in I. This is a strong indication that that the processes of integration and differentiation are interconnected. Table of Indefinite Integrals
