NCERT Books for Class 12 Maths Chapter 7 Integrals

ntegrals is an important chapter in Class 12 Mathematics and forms a major part of calculus. Integration is the reverse process of differentiation and is used to find functions, areas, and solutions to various mathematical and real-life problems. This chapter introduces the basic concepts and methods of integration.

What are Integrals?

Integration is a mathematical process used to determine the original function from its derivative. It helps in finding accumulated quantities and solving problems involving areas and rates of change.

Types of Integrals

Indefinite Integrals

Indefinite integrals represent a family of functions and include an arbitrary constant. They are used to find antiderivatives of given functions.

Definite Integrals

Definite integrals have fixed limits and are used to calculate the exact value of an integral over a specific interval.
