Data Analysis: students will have a comprehension of hypothesis testing as related to data analysis, and to use these ideas in the context of simple linear regression and one-way analysis of variance. They will be able to apply these techniques to analyse the type of data that arises in engineering practice. |

Multivariable Calculus: Describe a spatial motion problem in terms of a paraemterised position vector and determine the associated velocity vector and acceleration vectors. Compute the unit tangent vector for a parameterised path by normalising the velocity vector. Compute the tangential and normal components of acceleration via the projection of vectors (using the dot product). Identify motion that is parameterised in terms of arc length. Calclulate the arc length travelled along a path via a line integral. Calculate the work done by a force applied along a path by integrating the dot product of a force and velocity vector along a line. Compute partial derivatives. Compute rates of change for multivariable functions by application of the multivariable chain rule. Use computer software to visualise multivariable functions of 2 variables as surfaces. Apply multivariable optimisation techniques to find and classify critical points for functions of 2 variables. Explain the physical significance of grad, div and curl. Compute the Gradient of a scalar field to determine the direction of maximum rate of change and hence be able to calculate the directional derivative. Compute the Divergence of a given vector field, to determine whether it is zero and hence incompressible. Compute the Curl of a given vector field, to see if it is zero and hence whether it is irrotational. Describe the volume beneath a surface over a region using multivariable integrals. Sketch the region of integration for a multivariable integral. Compute multivariable integrals using appropriate techniques, including change of order and change of variable. Compute the Jacobian for a given change of variable |

Basic Skills Quiz (4% of final grade).

Weekly Quizzes (10% of final grade).

Assignment 1 (8% of final grade).

Assignment 2 (8% of final grade).

Test 1 (10% of final grade).

Test 2 (10% of final grade).

Exam rules

The exam is worth 50% of the final grade. It is a 3 hour, closed-book and no calculator exam.

Inclusive learning

Students are urged to discuss privately any impairment-related requirements face-to-face and/or in written form with the course convenor/lecturer and/or tutor.

Other assessment rules

A 10% rule will operate. Specifically, the final mark may not exceed the exam mark by more than 10%.

Final grades in this course will be determined using the standard University of Auckland grade boundaries after rounding your final mark to the nearest integer.

All coursework mark queries must be lodged before the day of the final exam.

Academic integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting his or her learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the world-wide web. A student's assessed work may be reviewed against electronic source material using computerised detection mechanisms. Upon reasonable request, students may be required to provide an electronic version of their work for computerised review.

All students enrolled at the University of Auckland are required to complete a compulsory Academic Integrity course, usually in their first semester/year of enrolment. The University of Auckland’s full guidelines on procedures and penalties for academic dishonesty are available here.

This site intends to guide you through your chosen specialisation at the Faculty of Engineering. The semester links lets you view detailed course information for your chosen course. Please note that the structure displayed for your specialisation here will reflect what’s available over the upcoming semesters, but detailed information may be from a previous year.

All the information here is accurate at the time of publication, but you are are advised to additionally consult our official document, the University of Auckland Calendar, for accurate academic regulations, requirements, and policies.
