CBSE Class 12 Mathematics Notes also concentrates on other important concepts like differentiating inverse trigonometric functions and new functions like logarithmic and exponential functions. Differentiability means that the function has a derivative at a point. Continuity means that the limit from both sides of a value is equal to the function’s value. The list of topics covered under this chapter are:
 Introduction
 Continuity
 Differentiability
 Exponential and Logarithmic Functions
 Logarithmic Differentiation
 Derivatives of Functions in Parametric Forms
 SecondOrder Derivative

Chapter 7. Integrals.
The Integrals chapter deals with the study of definite and indefinite integrals and their elementary properties. The development of integral calculus arises to solve the problems of the following types:
 The problem of finding the area bounded by the graph function under certain conditions.
 The problem of finding the function whenever the derivatives are given.
These two problems lead to the development of integral calculus (definite integral and indefinite integral). The elaborate explanations of each topic covered under integrals are found in CBSE Class 12 Mathematics Notes.
 Introduction
 Integration as an inverse process of differentiation
 Some properties of indefinite integrals
 Geometrical interpretation of indefinite integral
 Integration by substitution
 Comparison between differentiation and integration
 Methods of integration
