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 adept of the cost curves has a particular shape, each(prenominal) of the others has a! nother speci?c shape. The positions at which the average and marginal curves cross one another bum also be exactly determined.
