Let’s check the following solutions: ## Chapter 1: Relations and Functions

This section covers NCERT Solutions for Class 12 Maths Chapter 1 – Relation and functions and discusses the introduction of relations and functions, types of relations, types of functions, the composition of functions and invertible functions, binary operations, and miscellaneous examples.

Here, are a total of five exercises covered in this Chapter. Exercise 1.1 is only based upon the topic types of relations: reflexive, symmetric, transitive, and equivalence relations while the rest of the exercises 1.2, 1.3, and 1.4 are based on one-to-one and onto functions, composite functions, the inverse of a function.

However, miscellaneous exercises cover standard problems based on all the mentioned topics in this Chapter.

## Chapter 4: Determinants

Chapter 4 of Class 12 Maths Solutions discusses the topic of Determinants. Students will get to learn about the definition and meaning of determinants, remarks based on the order of determinants, properties of determinants, finding the area of a triangle using determinants, minors and cofactors of determinants, adjoint of a matrix, the inverse of a matrix, applications of determinants, and matrices and miscellaneous examples.

Below we have links provided to each exercise solution covered in this Chapter. The first exercises are based on the determinant of a square matrix (up to 3 × 3 matrices), properties of determinants, minors, co-factors, and applications of determinants in finding the area of a triangle.

However, the rest of the five exercises are based on the concepts of Adjoint and inverse of a square matrix. Consistency, inconsistency, and the number of solutions of a system of linear equations by examples, solving system of linear equations in two or three variables (having unique solution) using the inverse of a matrix.

## Chapter 5: Continuity and Differentiability

Chapter 5 of Class 12 Maths Solutions starts with the definition of Continuity. Students go on to learn about continuity, algebra of continuous function, definition and meaning of differentiability, derivatives of composite functions, derivative of implicit functions, the derivative of inverse trigonometric functions, exponential and logarithmic functions, logarithmic differentiation, derivatives of functions in parametric forms, second-order derivatives, mean value theorem via miscellaneous examples.

Here, students can find the exercises explaining these concepts properly with solutions. The first five exercises deal with problems based on Continuity and differentiability, the derivative of composite functions, chain rule, inverse trigonometric functions, and the derivative of implicit functions. Concept of exponential and logarithmic functions

While the rest of the exercises are typically based on the questions of Derivatives of logarithmic and exponential functions. Logarithmic differentiation is the derivative of functions expressed in parametric forms. Second-order derivatives. Rolle’s and Lagrange’s Mean Value Theorems (without proof) and their geometric interpretation.
