Application of calculus in economics

Abstract

Mathematics is increasingly widely applied in many fields of science as well as in economics and life. Increasing the application of economic problems with practical content in teaching Mathematics is necessary and consistent with the goals of Mathematics. One of the tools to solve economic problems is integration. This article provides some applications of integration to determine the total function when knowing the marginal value function, determine the capital fund function according to the investment function, calculate consumer surplus and producer surplus, and the average value of the function.
