Topics Covered in Exercise 9.1 Class 12 Mathematics Questions

Ex 9.1 class 12 maths solutions cover the topic of basic concepts of differential equations like order of a differential equation and degree of a differential equation. eSaral’s experts of mathematics have  provided detailed explanations of these topics for students to perform well in examinations.

1. Basic Concepts of Differential Equations

An equation involving derivatives of the dependent variable with respect to independent variable (variables) is known as a differential equation.

A differential equation involving derivatives of the dependent variable with respect to only one independent variable is called an ordinary differential equation.

• Order of a differential equation

Order of a differential equation is defined as the order of the highest order derivative of the dependent variable with respect to the independent variable involved in the given differential equation.

• Degree of a differential equation

Degree of a differential equation is defined if it is a polynomial equation in its derivatives.

By the degree of a differential equation, when it is a polynomial equation in derivatives, we mean the highest power (positive integral index) of the highest order derivative involved in the given differential equation.
