Course unit partition: MATHEMATICS

Learning objectives

THE COURSE AIMS TO PROVIDE BASIC MATHEMATICAL KNOWLEDGE THAT WILL ENABLE THE STUDENT TO DESCRIBE AND ANALYSE ECONOMIC AND BUSINESS PROBLEMS IN A STRUCTURED WAY AND TO ADEQUATELY USE THE MOST SUITABLE TOOLS OF CALCULUS FOR SOLVING THEM.
COMPETENCES THAT CAN BE ACQUIRED
AT THE END OF THE COURSE THE STUDENT WILL HAVE ACQUIRED THE NECESSARY QUANTITATIVE TOOLS FOR DISCERNING THE STRUCTURE OF A PROBLEM FROM THE CONTEXT, FOR THE PURPOSE OF UNDERSTANDING AND SUCCESSFULLY COMMUNICATING WHAT IS NEEDED FOR TAKING THE MOST SUITABLE ECONOMIC DECISIONS IN A SUFFICIENTLY INFORMED WAY. IN PARTICULAR, THE STUDENT WILL BE ABLE TO READ A GRAPH, INTERPRET A TABLE, CORRECTLY DECIPHER QUANTITATIVE INFORMATION TAKEN FROM THE INTERNET, AND ALSO CONSTRUCT A USEFUL MATHEMATICAL MODEL (AT LEAST IN THE SIMPLEST CASES) FOR SOLVING MICRO AND MACRO-ECONOMIC PROBLEMS.
