Chapter 2

Univariate and multivariate calculus

Abstract

This chapter introduces the essential techniques for the numerical standard calculus that will be used throughout the whole book. It represents therefore the basis, to understand the way the static optimization in Part II, the dynamic modeling, as well as the dynamic optimization in Part III have been applied with Excel. This chapter will try to execute and grasp with Excel the geometric interpretation of the differentiation and integration, so that the way calculus is applied to economics will be somehow easier to understand. This chapter has been divided into numerical differentiation, partial differentiation, and numerical integration. The last paragraph describes some applications ...
