Introduction

Today’s techniques for solving optimisation problems are essential in business and various fields of research.

In Mathematics 2 we will discuss optimisation problems with functions of more than one variable, and study the mathematical techniques required for solving these problems.

 

 

Pre-course requirements

It is recommended that before enrolling in this module students have completed courses on linear algebra and differential calculus with one variable.

Objectives

The main objectives of this course are to acquire a good command of the functions of several variables, especially their derivatives, and to know how to plan and solve problems of maximums and minimums with more than one variable.

Teaching and learning activities

In person

Theoretical aim:

The theory behind each of the topics in the course programme is shown in detail, yet avoiding excessive formality that could mask the true purpose of the course, which is to apply mathematical language to economics. For this reason, abstract mathematical concepts are illustrated using applications and practical problems in economic terms.

Practical aim:

The concepts should be consolidated by solving the problems given to the students throughout each chapter. These problems will be resolved and discussed in class. It would also be useful for students to solve further problems from the recommended books in the bibliography.

Evaluation systems and criteria

In person

The module will be evaluated on the basis of three elements: continuous evaluation, mid-course examination and final examination, and as follows:

Continuous evaluation

15%

15%

Mid-course examination

15%*

30%*

Final examination

70%*

55%*

* This percentage will be determined by the mark obtained in the mid-course examination

Second sitting

For students taking the second-sitting examination, evaluation will take place as follows:

Continuous evaluation

15%*

Final examination

85%

* The continuous evaluation mark will be the same as for the first sitting.
