## NCERT Solutions for Class 12 Maths Chapter 7- Integrals

The chapter integrals belongs to the unit Calculus, that adds up to 35 marks of the total marks. There are 11 exercises along with a miscellaneous exercise in this chapter to help the students get thorough with the concept of Integrals. The Chapter 7 of NCERT Solutions for Class 12 Maths discusses the following:

1. Integration is the inverse process of differentiation. In the differential calculus, we are given a function and we have to find the derivative or differential of this function, but in the integral calculus, we are to find a function whose differential is given. Thus, integration is a process which is the inverse of differentiation.
2. From the geometric point of view, an indefinite integral is collection of family of curves, each of which is obtained by translating one of the curves parallel to itself upwards or downwards along the y-axis.
3. Some properties of indefinite integrals.
4. Some standard integrals
5. Integration by partial fractions
6. Integration by substitution: A change in the variable of integration often reduces an integral to one of the fundamental integrals. The method in which we change the variable to some other variable is called the method of substitution. When the integrand involves some trigonometric functions, we use some well known identities to find the integrals.
7. Integration by parts: the integral of the product of two functions = first function × integral of the second function – integral of {differential coefficient of the first function × integral of the second function}.
8. First fundamental theorem of integral calculus.
9. Second fundamental theorem of integral calculus.
