# Module MAU22E01: Engineering Mathematics III 2021

## School of Mathematics, Trinity College

### Lecturer Dmitri Zaitsev

Requirements/prerequisites: MAU11E01, MAU11E02
Number of lectures per week: 3 + 1 tutorial (tutorials starting week 2)
Duration: 11 weeks

The Annual Exam will have 6 questions. Credit will be given for the best 5 questions. Assignments count 10% and Final Exam 90%. Supplemental Exam counts 100%. Examination material is within the scope of the problem sheets.

### Organization and Content:

For up-to date information, please see the module page MAU22E01-A-SEM101-202122 ENGINEERING MATHEMATICS III on TCD Blackboard.

### Lectures:

To be posted regularly to Blackboard as videos with slides, starting from week 1. I'll be sending respective announcements through Blackboard at the beginning.

### Tutorials:

Starting week 2, see Blackboard announcements to come for more details.

### Homework:

Problem sheets will be posted in advance for each tutorial. Only some of the sheets will be marked (not the first sheet), to ease the burden of the online submission and marking, and contribute for 10% of your total mark. It is important to be able to do all the problems, including unmarked ones, to ensure you are prepared for the exam.
