Integration comes under Calculus which is one of the very important topics of physic
Integration means in simple word submission or getting together collectively known as integration. ?

an integral assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinitesimal data. The process of finding integrals is called integration.

Integration is the process of finding an anti-derivative of a given function f. ‘Integrate f’ means ‘find an anti-derivative of f’. Such an anti-derivative may be called an indefinite integral of f and be denoted by ∫f(x) dxThe term ‘integration’ is also used for any method of evaluating a definite integral.The definite integral can be evaluated if an anti-derivative Φ of f can be found, because then its value is Φ(b) − Φ(a). (This is provided that a and b both belong to an interval in which f is continuous.)However, for many functions f, there is no anti-derivative expressible in terms of elementary functions, and other methods for evaluating the definite integral have to be sought, one such being so-called numerical integration.

When we add infinite number of infinitelysmally numbers , it is known as integration.For example del x + del x + ……….n terms .

Integration is a way of adding slices to find the whole. Integration can be used to find areas, volumes, central points and many useful things.
