Linear Algebra and Calculus for Economic and Business Problems

Andrianos Tsekrekos - Undergraduate - (A-)
Accounting & Finance, Athens University of Economics and Business

The course aims to thoroughly cover the basic principles and methods of calculus and linear algebra that are considered to be essential to the qualified financial analyst/ accountant today. In order to achieve this goal, this course develops aspects of algebra, analysis, and differential and integral calculus, which are the mathematical background of quantitative tools of modern financial and accounting theory.
