Topics Covered in RS Aggarwal Solutions for Chapter 18 – Differential Equations and Their Formation

Introduction:

An equation that contains one or more functions with its derivatives is called a differential equation. The derivatives of the function tell us about the rate of change of a function at a point. It is mainly utilized in fields like physics, engineering, biology, and so on. The primary purpose of the differential equation is the study of solutions that satisfy the equations, and hence the properties of the solutions. One of the simplest ways to solve the differential equation is by using explicit formulae. Here we will talk about the definition, types, methods to solve the differential equation, ordinary differential equations.

Differential Equation Definition:

A differential equation is an equation which contains one or more terms which involve the derivatives of one variable (i.e., dependent variable) with respect to the other variable (i.e., independent variable)

dy/dx=f(x)

where x the independent variable and y is the dependent one.

For example, dy/dx = 5x

Differential Equation Types:

Differential equations are of the following types:

  1. Ordinary Differential Equations
  2. Partial Differential Equations
  3. Linear Differential Equations
  4. Non-linear differential equations
  5. Homogeneous Differential Equations
  6. Non-homogenous Differential Equations

Differential Equations Solutions:

To find the solution of the differential equations, there are two methods to solve differential function.

  1. Separation of variables
  2. Integrating factor

Ordinary Differential Equation:

A Differential equation that involves a single function and its derivatives is called an ordinary differential equation. It has only one independent variable and may contain one or more of its derivative with respect to the variable.

ODE of nth order has the following general form:

F(x, y, y, …,yn ) = 0

Applications:

Some of the applications of differential equations are:

  1. Differential equations describe various exponential growths and decays.
  2. They are used to determine the change in investment return over a given time period.
  3. They are used in the field of medical science for modelling cancer growth or the spread of disease in the body.
  4. The movement of electricity can also be described with the help of it.
  5. They help economists in finding optimum investment strategies.

The various other applications in engineering are: ­ heat conduction analysis, in physics it can be used to understand the motion of waves. The ordinary differential equation can be utilized as an application in the engineering field like for finding the relationship between various parts of the bridge.
