Chapter 4. Determinant.

A Determinant is the numerical value of the square Matrix. You can define the determinant of a matrix as a Scalar value that can be calculated from the elements of a square Matrix. The determinant of a matrix is always positive. Determinants are built to determine the uniqueness of solutions associated with matrices, which are used to express Algebraic Equations. Determinants are applied in Economics, Engineering and Science. The topics covered in determinants in CBSE Class 12 Mathematics Notes are listed below:

In Continuity and Differentiability chapter Class 12, you will learn essential concepts of differentiability, continuity, and their relationship. 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
Second-Order Derivative
Mean Value Theorem

Chapter 6. Application of Derivatives.

In this chapter, you will learn how to determine the rate of change of quantity, find the equations of tangents, find turning points on the graphs for various functions, maxima and minima. CBSE Class 12 Mathematics Notes guide you on how to relate different applications of derivatives in multiple fields like Engineering, Science and varied amounts of calculations for Businesses to develop profit-loss strategies for future investments. Below are the topics covered in the application of derivatives.

Introduction
Increasing and Decreasing Functions
Rate of Change of Quantities
Approximations
Tangents and Normals
Maximum and Minima
Maxima and Minima

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

A Differential Equation is a Mathematical equation that involves variables like x or y and the rate at which those variables change. The differential equations are unique because the solution of a differential equation is itself a function instead of a number. The differential equations are classified into the following:

Ordinary Differential Equations.
Partial Differential Equations.

Nonlinear Differential Equations.
Homogeneous Differential Equations.
Non-homogeneous Differential Equations.

The Ordinary differential equations and the Partial differential equations are considered the most essential and standard differential equations.

This is the basic Probability theory, which is also applied in the Probability distribution, where you will learn the possibilities of the outcomes for a random observation. The CBSE Class 12 Mathematics Notes help students judge the accuracy of an event by analysing seemingly persuasive data. This gives students a solid introduction to Probability Mathematics while studying both advantages and limitations of applying Probability theory to different situations under varied conditions.
