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.

May 28, 2023 · The Definition of the Definite Integral. In this section we give a definition of the definite integral \(\displaystyle \int_a^b f(x)\,d{x}\) generalising the machinery we used in Example 1.1.1. But first some terminology and a couple of remarks to better motivate the definition.
We find the Definite Integral by calculating the Indefinite Integral at a, and at b, then subtracting: Example: What is. We are being asked for the Definite Integral, from 1 to 2, of 2x dx. First we need to find the Indefinite Integral. Using the Rules of Integration we find that ∫2x dx = x2 + C. Now calculate that at 1, and 2: Subtract:
We can approximate integrals using Riemann sums, and we define definite integrals using limits of Riemann sums. The fundamental theorem of calculus ties integrals and derivatives together and can be used to evaluate various definite integrals.
In calculus, an integral is a mathematical object that can be interpreted as an area or a generalization of area. Integrals, together with derivatives, are the fundamental objects of calculus. Other words for integral include antiderivative and primitive.
In mathematical terms, we would describe a definite integral as “the integral of the function $$f(x)$$ with respect to the variable $$x$$, on an interval $$[a, b]$$.” If you just look at those mathematical descriptions or expressions all at once, it can be a bit overwhelming.
In calculus, an integral is a mathematical object that corresponds to summing infinitesimal data that may describe concepts such as displacement, area, and volume. The process of computing an integral is referred to as integration, and it is the inverse operation of differentiation.
