# MATH2921: Vector Calculus and Differential Eqs (Adv)

## Overview

This is the advanced version of MATH2021, with more emphasis on the underlying concepts and mathematical rigour. The vector calculus component of the course includes: parametrised curves and surfaces, vector fields, div, grad and curl, gradient fields and potential functions, Lagrange Multiplier Method, line integrals of different types (arc length, work, etc.), conservative fields, double and triple integrals, change of variable formulas, polar, cylindrical and spherical coordinates, areas, volumes and mass, flux integrals, and Green's Gauss' and Stokes' Theorems. The Differential Equations component of the course focuses on ordinary and partial differential equations (ODEs and PDEs) with applications with more complexity and depth. It provides a more thorough grounding in these techniques to enable students to build on the concepts in their subsequent courses. The main topics are: first and second order ODEs (including inhomogeneous equations), series solutions near a regular point, higher order ODEs and systems of first order equations, matrix equations, various methods (variation of parameters, undetermined coefficients, reduction of order), an introduction to PDEs, and first methods of solutions (including separation of variables, and Fourier Series). It could extend to the Laplace and Fourier Transform and elementary Sturm-Liouville Theory.

### Assessment summary

Assignment: require students to integrate information from lectures and practice classes to create a concise written argument. Test your understanding of material covered in the vector calculus and differential equations components of the course.

Final Exam: cover all material in the unit from lectures, tutorials and practice classes.

Replacement Final Exam: if a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam). The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator.

### Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name

Mark range

Description

High distinction

85 - 100

Representing complete or close to complete mastery of the material

Distinction

75 - 84

Representing excellence, but substantially less than complete mastery

Credit

65 - 74

Representing a creditable performance that goes beyond routine knowledge and understanding, but less than excellence

Pass

50 - 64

Representing at least routine knowledge and understanding over a spectrum of topics and important ideas and concepts in the course.

Fail

0 - 49

When you don’t meet the learning outcomes of the unit to a satisfactory standard.

### Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

• Deduction of 5% of the maximum mark for each calendar day after the due date.
• After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

Assignment: for late submission, every day (after due time) costs 20% of the original weight. Quiz: no late submission or replacement quiz will be accommodated. The weight can be moved to Final Exam after successful application through the University. Final Exam: subject to the university policy.

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

## Learning support

### Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

### Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

### Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

### Attendance and class requirements

Class attendance is strongly recommended but not counted directly in course marks.

We plan to take partial attendance count in lectures and practice classes throughout the semester whenever possible for teaching data.

### Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

The unit will be based on a mixture of typed and (in-class) handwritten lecture notes provided throughout the semester. All lecture notes from Year 2022 will be provided at the beginning of the semester.

The following references are recommended but not required. All references for this unit can be accessed through the Library eReserve, available on Canvas.

## Learning outcomes

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

• LO1. Demonstrate a conceptual understanding of vector-valued functions, partial derivatives, curves and integration over a region, volume and surface as well as solving basic differential equations with a background in a variet of techniques and applications of mathematical analysis.
• LO2. Understand the definitions, main theorems, propositions, lemmata and corollaries for multivariate calculus as well as their applications to science. Also understand and the main theorems and methods of solving elementary linear differential equations as well as the applications.
• LO3. Be fluent in the computation of integrals via substitution and coordinate transform methods.
• LO4. Develop an appreiciation and strong working knowledge of the theory and applications of elementary vector analysis and differential equations.
