1. The course includes the mathematical techniques and economic applications of derivatives, matrix algebra, differentials, multivariable optimization, constrained optimization and integration.
2. Emphasis is on the application of optimization, both with and without constraints, and introductory integrals for understanding relationships of various economic variables and concepts, such as the relationship of aggregate, average and marginal functions
3. The aim is to give students the mathematical tools they need for further study in economics, therefore, this course is designed to provide strong mathematical foundations.
