Integral - Wikipedia
In mathematics, an integral is the continuous analog of a sum, which is used to calculate areas, volumes, and their generalizations. Integration, the process of computing an integral, is one of the two fundamental operations of calculus, [a] the other being differentiation.
Lists of integrals - Wikipedia
Integration is the basic operation in integral calculus. While differentiation has straightforward rules by which the derivative of a complicated function can be found by differentiating its simpler component functions, integration does not, so tables of known integrals are often useful. This page lists some of the most common antiderivatives.
Line integral - Wikipedia
In mathematics, a line integral is an integral where the function to be integrated is evaluated along a curve. [1] The terms path integral, curve integral, and curvilinear integral are also used; contour integral is used as well, although that is typically reserved for line integrals in the complex plane.
Multiple integral - Wikipedia
In mathematics (specifically multivariable calculus), a multiple integral is a definite integral of a function of several real variables, for instance, f(x, y) or f(x, y, z).
List of definite integrals - Wikipedia
In mathematics, the definite integral. is the area of the region in the xy -plane bounded by the graph of f, the x -axis, and the lines x = a and x = b, such that area above the x -axis adds to the total, and that below the x -axis subtracts from the total.
Integral - Simple English Wikipedia, the free encyclopedia
In calculus, an integral is the space under a graph of an equation (sometimes said as "the area under a curve"). An integral is the reverse of a derivative, and integral calculus is the opposite of differential calculus. A derivative is the steepness (or "slope"), as the rate of change, of a curve.
Integral equation - Wikipedia
In mathematics, integral equations are equations in which an unknown function appears under an integral sign. [1] . In mathematical notation, integral equations may thus be expressed as being of the form: where is an integral operator acting on u.
