It gives the rate of change of one variable with respect to others. This page lists some of the most common antiderivatives $\int {kdx = kx + c} $ where $k$ is a constant. And/or half angle formulas to reduce the integral into a form that can be integrated.
Some generalized results obtained using the fundamental theorems of integrals are remembered as integration formulas in indefinite integration.

Strip 2 secants out and convert rest to tangents using sec 1 tan22x x. (i) when you find integral ∫g (x) dx then it will not contain an arbitrary constant. There are 3 types of integration methods and each method is applied with its.
∫ k f (x) dx = k ∫ f (x) dx, where k ∈ r.
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. Since integration is almost the inverse operation of differentiation, recollection of formulas and processes for differentiation already tells the most important formulas for integration: Applications of each formula can be found on the following pages. The integral of the sum or difference of a finite number of functions is equal to the sum or difference of the integrals of the individual functions.
The process of finding the integral is integration.
(ii) ∫g (x) dx should be taken as the same in both terms. Dx = a x /loga+ c. (ii) ∫ d x a x + b dx = 1 a ln|ax+b| + c. If f is an antiderivative of f, then f(x)dx = f(x) + c is called the (general) indefinite integral of f, where c is an arbitrary constant.

We urge all the scholars to first learn the integration formulas and then practice the application of these formulas, in order to solve any sum of integration. ∫(ex) = ex +c ∫ ( e x) = e x + c.
