Introduction To Mathematical Modeling NCERT Book Class 9

A2.1 Introduction

Right from your earlier classes, you have been solving problems related to the real-world around you. For example, you have solved problems in simple interest using the formula for finding it. The formula (or equation) is a relation between the interest and the other three quantities that are related to it, the principal, the rate of interest and the period. This formula is an example of a mathematical model. A mathematical model is a mathematical relation that describes some real-life situation.

Mathematical models are used to solve many real-life situations like:

• launching a satellite.

• predicting the arrival of the monsoon.

• controlling pollution due to vehicles.

• reducing traffic jams in big cities.

In this chapter, we will introduce you to the process of constructing mathematical models, which is called mathematical modelling. In mathematical modelling, we take a real-world problem and write it as an equivalent mathematical problem. We then solve the mathematical problem, and interpret its solution in terms  f the real-world problem. After this we see to what extent the solution is valid in the context of the real-world problem. So, the stages involved in mathematical modelling are formulation, solution, interpretation and validation.

We will start by looking at the process you undertake when solving word problems, in Section A2.2. Here, we will discuss some word problems that are similar to the ones you have solved in your earlier classes. We will see later that the steps that are used for solving word problems are some of those used in mathematical modelling also.
