Module Code: MTH004
Module Title: Multivariable Calculus (Business and Arts)
Module Level: Level 0
Module Credits: 5.00
Academic Year: 2019/20
Semester: SEM2
Originating Department: Mathematical Sciences
Pre-requisites: MTH013ORMTH019ORMTH023ORMTH025ORMTH027ORMTH021
To give students an education in calculus of multivariable functions, differential equation and infinite series, which includes the basic topics usually covered in an elementary course of multivariable calculus.

To give students an appreciation of the application of mathematics to social sciences and others.

To introduce the concept of modelling and various mathematical models in practical problems.

To develop students' ability to work independently and to acquire the skill of problem solving.

Learning outcomes 
On successful completion of this module, students are expected to

have an initial understanding of the basic concepts which are the subject of this module;

have a good appreciation of the link between mathematics and other subjects;

have the basic skills of problem solving;

be able to understand the mathematical models for simple practical problems.
Method of teaching and learning 
Students will be expected to attend about five hours of formal lectures and supervised problem classes/tutorials in a typical week. Lectures and tutorials will introduce students to the academic content and practical skills which are the subject of the module, while problem classes and tutorials will allow students to practice those skills.

Seminars and group discussions will help students to access the various applications of calculus and develop the ability of independent learning and research.

In addition to contact hours, students will be expected to devote sufficient unsupervised time to private study. Private study will provide time for reflection and consideration of lecture material and background reading.

Continuous assessment including home assignment marking will be used to test to what extent practical skills have been learnt. Written examinations in the middle and at the end of the module constitute the major part of assessment of the academic achievement.

In order to facilitate the smooth transition to the English delivery of all modules from year 2, this module will be delivered in dual languages (Chinese and English).
