Application of Calculus in Commerce and Economics
OP Malhotra ISC Class-12 Maths Ch-26
Application of calculus in commerce and economics:-
Introduction:
Quantitative techniques and mathematical models are now being increasingly used in business and economic problems. Differential calculus is used while determining the rate of change of a given function (dependent variable) due to change in one of the independent variables. Integration is the inverse of differentiation and it involves finding a function whose rate of change is given. In this chapter, we shall start with the a few basic concepts of economics—fixed and variable cost, average cost, revenue, profit etc., and then go on to marginal functions (marginal cost and marginal revenue) using first derivative. We shall use second derivatives to find minimum costs and maximum revenue or maximum profit.
Demand function:
Various economic studies show that the quantity demanded of a commodity depends upon many factors, viz., price of the commodity, consumer’s income, taste of the consumer, price of other related commodities etc. To simplify things, we will consider the relationship between demand and price of the commodity only, assuming that all other factors remain constant.
