Ans. Examples of modelling.
(i) Mathematical modelling is a potential advantage to industries. Models are used to quickly explore new solutions and innovations that can save time and money in the development and validation phases. e.g. in a T.V. industry for innovative designs, multiple testing and optimization for efficiency.
(ii) For weather prediction, mathematical model of the atmospheric motions are based on well known equations and phenomena. For a realistic and useful description, all the subsystems have to be modelled to study their behaviour and interactions.
