## NCERT Solutions for Class 12 Maths Chapter 9- Differential Equations

The chapter Differential Equations belongs to the unit Calculus, which adds up to 35 marks of the total marks. There are 6 exercises along with a miscellaneous exercise in this chapter to help students understand the concepts of Differential Equations clearly. Chapter 9 of NCERT Solutions for Class 12 Maths discusses the following:

1. An equation involving derivatives of the dependent variable with respect to the independent variable (variables) is known as a differential equation.
2. The order of a differential equation is the order of the highest order derivative occurring in the differential equation.
3. The degree of a differential equation is defined if it is a polynomial equation in its derivatives.
4. The degree (when defined) of a differential equation is the highest power (positive integer only) of the highest order derivative in it.
5. A function which satisfies the given differential equation is called its solution. The solution which contains as many arbitrary constants as the order of the differential equation is called a general solution and the solution free from arbitrary constants is called a particular solution.
6. To form a differential equation from a given function, we differentiate the function successively as many times as the number of arbitrary constants in the given function and then eliminate the arbitrary constants.
7. The variable separable method is used to solve such an equation in which variables can be separated completely, i.e. terms containing y should remain with dy, and terms containing x should remain with dx.
