As you 2 FUNCTIONS IN ECONOMICS progress in economics you will ?nd mathematics is used in various ways in textbooks and in journal articles. In introductory economics you study the relationship between various cost curves such as average variable cost, total cost and marginal cost. Mathematics makes relationships obvious and tells us that if 1 of the cost curves has a particular shape! , each(prenominal) of the others has another speci?c shape. The positions at which the average and marginal curves cross one another lot also be exactly determined. In measuring shot of demand there can be ambiguity, but mathematics gives us a very(prenominal) measure in the form of point elasticity, and this resolves the dif?culty. Economic models overwhelm those representing supply and demand in a market, and...If you want to get a full essay, order it on our website: OrderCustomPaper.com
