## NCERT Solutions for Class 12 Maths Chapter Brief

The class 12 Maths book is divided into two parts. Part one has six chapters, while Part 2 has seven chapters. Class 12 students would have to prepare for their exam with all 13 chapters in the Maths chapter list class 12. The 12th CBSE Maths solutions are designed to provide a better understanding of Mathematical concepts in the class 12 Maths NCERT book.

Easy language or a reduced syllabus do not make Maths easy; it is all about precision, accuracy, and numbers. The subject matters that have created class 12 Mathematics solutions understand this paradox. **The class 12 Maths NCERT solutions are strictly based on the Maths class 12 chapters.** The chapter brief for class 12 Maths NCERT book all chapters are given below:

### Part 1

**Chapter 1: Relations and Functions**

The first chapter of plus two Maths chapters focuses on different types of relations and functions, the composition of functions, invertible functions, and binary operations. The concept has been well-explained with many examples. The highlights of this chapter are;

- Ordered pairs
- Cartesian product of sets
- Number of elements in the Cartesian product of two finite sets
- Cartesian product of the set of reals with itself (upto RxRxR)
- Definition of relation, pictorial diagrams, domain, co-domain, and range of a relation
- Function as a special type of relation
- Pictorial representation of a function, domain, co-domain, and range of a function
- Real valued functions, domain, and range of these functions, constant, identity, polynomial, rational, modulus, signum, exponential, logarithmic, and greatest integer functions, with their graphs
- Sum, difference, product, and quotients of functions

Solutions for class 12 Maths finely define the concepts for students to have a better understanding.

**Chapter 2: Inverse Trigonometric Functions**

The second chapter is a step ahead of what students learned in class 11, Trigonometry. Inverse Trigonometric Functions throw light on the restrictions on domains and ranges of trigonometric functions, ensuring the existence of their inverse and observing their behaviour through graphical representations. Trigonometry is one of the most important topics for students, as it is also used in Science and Engineering. Students who want to pursue these fields in the future must have proper knowledge of Trigonometry. Our subject matter experts know this topic's importance and have formulated the 12th Maths solution book that acts as the perfect study material for you. The chapter covers the following major areas;

- Definition
- Range
- Domain
- Principal value branch
- Graph of inverse trigonometric functions

**Chapter 3: Matrices**

Maths experts design Class XII Maths NCERT solutions as a tool to help class 12 students practice the Maths problems. The third chapter for class 12 Maths would include the following;

- Concept
- Notation
- Order
- Equality
- Types of matrices
- Zero and identity matrix
- Transpose of a matrix
- Symmetric and skew-symmetric matrices
- Operations on matrices: Addition and multiplication and multiplication with a scalar
- Simple properties of addition, multiplication, and scalar multiplication
- Non-commutativity of multiplication of matrices and the existence of non-zero matrices whose product is the zero matrix
- Invertible matrices and proof of the uniqueness of inverse, if it exists

**Chapter 4: Determinants**

Chapter 4 of the class 12 Maths NCERT book focuses on determinants up to order three only with real entries. The chapter will focus on various properties of determinants like Minors, Co-factors, Applications of determinants in finding the area of a triangle, adjoint, and inverse of a square matrix, consistency and inconsistency of system of linear equations, and solutions of linear equations in two or three variable using inverse of a matrix. The areas that are covered are;

- Determinant of a square (up to 3 X 3), minors, co-factors, and applications of determinants in finding the area of a triangle
- Adjoint and inverse of a square matrix
- Consistency, inconsistency, and number of solutions of a system of linear equations by examples, solving system of linear equations in two or three variables using the inverse of a matrix

Class 12 Maths NCERT book solution offers answers to all the topics under this chapter.

**Chapter 5: Continuity and Differentiability**

It deals with issues like maximising or minimising profit (cost) or minimum use of resources and is related to professional industries like Commerce, Management, Science, etc. This chapter from Mathematics Class 12 focuses on Linear Programming problems and their solutions by graphical method only. Chapter 12 of the class 12 NCERT book would cover the following;

- Introduction, related terminology such as constraints, objective function, optimization, graphical method of solution for problems in two variables, feasible and infeasible regions (bounded or unbounded)
- Feasible and infeasible solutions, optimal feasible solutions (up to three non-trivial constraints)

**Chapter 13: Probability**

Chapter 13 of NCERT class 12 textbook Maths deals with the important concept of the conditional probability of an event given that another event has occurred, which will help understand Bayes’ theorem, multiplication rule of probability and independence of events. The chapter will cover many important aspects of the concept that defines many things in our lives.
