INTEGRALS

NCERT Solutions for class 12 Chapter 7 Integral is all about the anti-derivative which is also called Integration.

TERMINOLOGIES OF INTEGRALS

Integration as an inverse method of Differentiation:It is a opposite process of differentiating a function as we are provided a derivative so that we could find the original function.

Geometrical Interpretation of Indefinite Integral:It is basically a geometrical representation of Integration.For Example:It is a graphical representation for Integral.

Properties of indefinite Integral:Here you’ll get every necessary properties of Integrals that will help to solve the further problems.

Differentiation and Integrations’s comparison:Here students will know how different is the differentiation from integration on the basis of properties.

Integration’s Method:Comparing to the last year’s session reduction of traditional method can be found with more properties of integration.

Integrating using Substitution Method:It is a simple method where you will learn how to integrate the problem by substituting a value.

Usage of Trigonometric Identities for Integration: Again there is an entry of Trigonometric Identities such as Sine,Cosine,Secant,Tangent,etc so that you use them while integrating a problem.

Besides this all you will be able to define the definite integrals as it has unique value and it is done by using a limit of a sum. Other terminologies like Fundamental Theorem of Calculus,Area function,First fundamental theorem of the integral calculus,Second fundamental theorem of the integral calculus,Evaluation of Definite Integrals by Substitution and Some Properties of Definite Integrals.

EXAMPLE SOLUTIONS FROM NCERT SOLUTIONS FOR CLASS 12 MATHS CHAPTER 7 INTEGRALS

1.

Solution:

 Let I = 

 ……….(i)

Putting 


To change the limits of integration from x to t

when x = 0, t = x2 +1 = 0 +1 = 1

when x =1, t = x2 +1 = 1 +1 = 2

 From eq. (i),

=

=

=

=  Ans.

2.

Solution:

Let I =  ……….(i)

Putting
