# BA Modern Language and Business & Management (Chinese) / Course details

Year of entry: 2024

Unit code ECON10071A 10 Level 1 Semester 1 Yes

### Overview

This unit provides students with the essential mathematical toolkit required by economics students. At the core of the unit are constrained, multivariate optimisation problems. Such problems form a core element of many economics units and students who took Advanced Mathematics will be familiar with the required solution techniques.

Students will also be introduced to the principles of matrix algebra, and of modelling dynamic variables.

Students will be provided with detailed material through lectures, tutorial, reading and online videos. A discussion board will allow students to receive frequent feedback on their understanding.

### Pre/co-requisites

A Level Maths or very good AS level

### Aims

The aim of this course is to introduce mathematical techniques useful in the economic and social sciences to those students who have the appropriate mathematical background.

### Learning outcomes

The objectives of this course are that students will be able to:

1. Solve simple linear equations, find roots a quadratic equations and understand the solution to non-linear equations.
2. Understand functions, continuity and basic differentiation.
3. Solve one and two-variable unconstrained and constrained optimisation problems using the Lagrangian method.
4. Demonstrate their understanding of linear univariate difference equations.

### Syllabus

The preliminary syllabus is

• Preliminaries and Pre-requisites. A review of your mathematical background and some observations on logic
• Functions & Univariate Calculus. Functions, continuity. Roots of equations. Limits and basic differentiation. Stationary points and optimisation. Concavity and convexity.
• Vectors and Matrices. An introduction to vectors and matrices: their mathematical manipulation - addition, multiplication. Inverse matrix. Determinants. Rank. Quadratic Forms.
• Bivariate Functions
Surfaces in 3D, contours. Partial functions and partial differentiation: the Jacobian and Hessian. Optimisation; saddle points. Concavity/convexity. Finding maxima/minima of functions of two variables subject constraints; e.g., maximising utility subject to a budget constraint.
