# MULTIVARIABLE CALCULUS - 2024/5

Module code: MAT1043

## Module Overview

This module introduces students to Multivariable Calculus in two and three dimensions, and selected topics such as differential operators and line integrals in Vector Calculus. This extends students’ knowledge developed in MAT1030 Calculus on differentiation and integration of single variable functions to partial differentiation, and double and triple integration of two and three-variable functions. This module provides the necessary ground work for modules such as MAT2047 Curves and Surfaces, MAT2050 Inviscid Fluid Dynamics, and MAT2054 Functions of a Complex Variable.

## Assessment Strategy

The __assessment strategy__ is designed to provide students with the opportunity to demonstrate:

- Understanding of key subject knowledge in multivariable differential and integral calculus, and differential operators and line integrals in vector calculus.
- The ability to identify and use the appropriate methods to solve unseen problems relating to multivariable calculus and vector calculus.

Thus, the

__summative assessment__for this module consists of:

- One in-semester test (50 minutes), worth 25% of the module mark, corresponding to Learning Outcomes 1, 2 and 3.
- A synoptic examination (2 hours), worth 75% of the module mark, corresponding to all Learning Outcomes 1 to 6.

Formative assessment

There are three formative unassessed courseworks over an 11 week period, designed to consolidate student learning. Students will also receive formative feedback at biweekly seminars on problem sheets, provided to students in advance and designed to consolidate student learning.

Feedback

Students will receive feedback on both the unassessed courseworks and the in-semester test. The feedback is timed such that feedback from the first coursework will assist students with preparation for the in-semester test. The feedback from all three courseworks and the in-semester test will assist students with preparation for the synoptic examination. This feedback is complemented by verbal feedback at biweekly seminars and at office hours.

## Module aims

- Provide students with a brief introduction to curves and surfaces in two and three dimensions, including revisiting lines and planes, and introducing conic sections and quadric surfaces.
- Introduce students to multivariable differential calculus, and enable them to find partial derivatives of two and three-variable functions.
- Introduce students multivariable integral calculus and enable them to calculate double and triple integrals.
- Develop students understanding of the differential operators div, grad and curl, and their properties. Enable them to calculus grad of a scalar field, and div and curl of a vector field.
- Enable students to calculate line integrals in two and three dimensions, and apply Green's theorem.

## Methods of Teaching / Learning

The __learning and teaching__ strategy is designed to:

- Provide students with a thorough introduction to multivariable differential and integral calculus.
- Introduce students to differential operators and line integrals in vector calculus.
- Provide students with experience of methods used to understand and solve problems in multivariable calculus and vector calculus.

The learning and teaching methods include:

- Four one-hour lectures for eleven weeks, with module notes provided to complement the lectures. These lectures provide a structured learning environment and opportunities for students to ask questions and to practice methods taught.
- Five seminars for guided discussion of solutions to problem sheets (provided to students in advance) to reinforce their understanding and guide their learning.
- Three assessed courseworks to provide students with further opportunity to consolidate learning. Students receive feedback on these courseworks as guidance on their progress and understanding.
- Lectures may be recorded or equivalent recordings of lecture material provided. These recordings are intended to give students an opportunity to review parts of lectures which they may not fully have understood and should not be seen as an alternative to attending lectures.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

## Other information

The School of Mathematics and Physics is committed to developing graduates with strengths in Digital Capabilities, Employability, Global and Cultural Capabilities, Resourceness and Resilience, and Sustainability. This module is designed to allow students to develop knowledge, skills and capabilities in the following areas:

**Digital Capabilities**: The SurreyLearn page for MAT1043 features a dynamic discussion forum where students can pose questions and engage with others using e.g. LaTeX and MathML tools. This enhances their digital competencies while facilitating collaborative learning and information sharing.

**Employability**: The module MAT1043 equips students with skills which significantly enhance their employability. The mathematical proficiency gained hones critical thinking and problem-solving abilities. Students learn to evaluate complex geometric problems and calculations, break them into manageable components, and apply logical reasoning to arrive at solutions — these are highly sought after skills in any profession.

**Global and Cultural Capabilities:** Student enrolled in MAT1043 originate from a variety of countries and have a wide range of cultural backgrounds. Students are encouraged to work together during problem-solving teaching activities in seminars and lectures, which naturally facilitates the sharing of different cultures.

**Resourcefulness and Resilience**: MAT1043 is a module which demands the ability to visualise geometric problems and perform lengthy unseen calculations accurately. Students will gain skills in analysing geometric problems using creative and lateral thinking, and will complete assessments which challenge them and build resilience.
