Roughly speaking
mathematical modelling is an activity in which we make models to describe the behaviour
of various phenomenal activities of our interest in many ways using words, drawings or
sketches, computer programs, mathematical formulae etc In earlier classes, we have observed that solutions to many problems, involving
applications of various mathematical concepts, involve mathematical modelling in one
way or the other Therefore, it is important to study mathematical modelling as a separate
topic In this chapter, we shall further study mathematical modelling of some real-life
problems using techniques/results from matrix, calculus and linear programming
