Abstract: Higher Mathematics in derivative is a very important concept, is to study an important tool for mathematical problem, while derivative areas in mathematics also have a very wide range of use. Marginal analysis in economics is one of their applications, and the marginal analysis is usually to optimize decision-making one of the basic quantitative methods, and closely related derivatives. In this paper, the theory expounded the concept of derivative and Economics in common ---- marginal analysis marginal cost, marginal revenue, marginal profits and the basic concept of derivative of marginal analysis in specific applications.
Key words: derivative, marginal analysis, decision-making
