Chapter Summary

--- PAGE 1 --- APPENDIX 2 INTRODUCTION TO MATHEMATICAL MODELLING 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 wri…
