# ENGR 121 (2019) - Home Page

Welcome to the home pages for ENGR 121: Engineering Mathematics Foundations.## Announcements

Our policy in ENGR121 on**showing working in assignments, Tests, and the Exam**, is that it is always a good idea to show working. Some questions will explicitly ask you to show working, and in that case you will need to show your working to get full marks. If working is not asked for, you can get full marks for a correct answer even if there is no working shown. An incorrect answer with no working shown cannot attract any marks; this is the danger of not showing your working. Exam Review Sessions

There will be multiple opportunities to review and get help before the exam. Keep an eye on the announcements.

EXAM REVIEW to go over old exams: Monday, 17 June, 2 PM - 6 PM in HMLT 104. Howard Lukefahr has started special tutorial sessions suitable for ENGR121 students who are having trouble with their mathematics, lecture material, tutorials, or assignments. Every Monday and Wednesday, 5pm to 8pm, in AM106. Tutorial signups are available here. Meanwhile, tuts have already started, and you can go to any tut you want no matter which one you sign up for. Lab signups will also be available on MyAllocator. Labs start on 18 March. The lectures are captured on video. Go to Blackboard to view them. Older announcements will go here.

## People

The Course Coordinator is Prof Mark McGuinness. Mark is lecturing the first six weeks, and Prof Peter Smith is lecturing the last six weeks. The Senior Tutor in charge of things administrative like assignments and tutorials and marking is Dr Steven Archer. Dr Howard Lukefahr is in charge of the labs, their supervision, report marking, and the lab content for this course. Howard is also offering special tutorials and events aimed at giving you extra help in this course (Mondays and Wednesdays 6-8pm in AM106). Howard is also available to students most times. There is a schedule on his door showing where he can be found pretty much all the time. The names of your tutors and lab demonstrators will appear shortly.## Class Representative

Well done, Sam, Cam, Ethan, Dylan and Elijah, for coming to the front of the whole class and giving election speeches. The class rep for ENGR121 is Dylan from Te Puke, and his email address is d.j.simpson2000 at live.com Dylan has set up a Facebook page for ENGR121 here. Thanks Dylan.## Discord

Here is a link to an online resource called Discord that provides an alternative to Facebook for ENGR121 students to text or chat with other ENGR students, many of whom are doing or have done ENGR121. Yes, it is oriented towards gamers but it is free and it probably hooks into the right community of students. Thanks to Matthew for suggesting this.## Extra Help

Howard Lukefahr has started special tutorial sessions suitable for ENGR121 students who are having trouble with their mathematics, lecture material, tutorials, or assignments.**Every Monday and Wednesday, 5pm to 8pm, in AM106**. There will be a mathematics Help Desk up here soon. The office hours of math and statistics academics are listed here.

## Lecture Notes

Lecture notes will be put here## Assignments and Tutorials and Answers

Please click for Assignments and Tuts, and model answers.## Test One

Two Tests will be given, each one held during a lecture time. Each Test is worth 10% towards your final grade. If you do better in the final exam, the Test will not be counted, and the exam will be worth 10% more (maximum mark). Test One will be held at 3:10pm on Thursday 4 April in MCLT103, our usual lecture room. It will cover all lectured material and lecture notes up to and including page 35 of the notes, solving quadratic and cubic polynomials. This includes also material covered in Tuts and Assignments 1-3. This formula sheet will be provided with the Test and with the Exam. It has been updated to include the names of sets of numbers.### Examples of Test One

- Here is a sample Test One, from 2018. Note that we will not test asymptotes of rational functions in Test One 2019, since we have not covered these yet in Assignment 3.
- Answers to Test One 2018.
- Sample Test One from 2017. Howard will use this for revision Weds night, 3 April. 6-8pm AM106. Questions 7 and 8 are not relevant to this year, as that material has not yet been taught.
- Answers to 2017 Test One.
- Sample Test One from 2016.
- Answers to 2016 Test One.

## Test Two

Test Two will be held at 3:10pm on Thursday 23 May in MCLT103. See the 2018 test which shows the formula sheet you will be given with the test. The format will be the same as 2018. Q1 on differentiation. Question 2 on integration. Q3 on vectors. The formula sheet gives a table of derivatives and integrals. It also gives the rules for: integration by parts, the product rule, the quotient rule, the chain rule. No formulae are provided for vectors. You will need to remember how to find: the magnitude of a vector, vector sums, vector dot products, the angle between 2 vectors, the vector equation of a line.- Sample Test Two from 2016 with solutions.
- Sample Test Two from 2016 with NO solutions.
- Sample Test Two from 2017 with solutions.
- Sample Test Two from 2018 with solutions.

## Final Exam

You must be available to sit the final two-hour exam during the exam period at the end of Trimester One. Note that the exam is two hours long this year, whereas in all previous years it was three hours long. This formula sheet will be provided with the Test and with the Exam. It has been updated to include the names of sets of numbers.### Previous Exams

Past exam papers are found on the library page: Go this page and EXAM PAPERS is an option at the top. Click and search for ENGR121. You'll find exam papers since 2014. https://library.victoria.ac.nz/library/ Here are some past exams and some model answers. Note that these past exams were three hours long, so they are bigger and longer than the exam will be this year.## Textbook

The textbook for ENGR 121 is:*Engineering Mathematics: A Foundation for Electronic, Electrical, Communications and Sytems Engineers (4th Edition)*, by Anthony Croft, Robert Davison, Martin Hargreaves and James Flint, Pearson, 2012. We follow this book very closely, and it is also the text for ENGR 122 Engineering Mathematics with Calculus, so it will be very useful. It costs about $144 at Vic Books. It is recommended, not required, since the lecture notes are so detailed. Also recommended, but not required, is

*Engineering Mathematics*, by K.A. Stroud, with Dexter J. Booth, Palgrave MacMillan, London. About $133 at Vic Books. Detailed lecture notes will also be posted on the course homepages from week to week.

## Assessment

To expand on the official assessment notes in the Course Outline, here is how your percentage mark is calculated, on which your final grade is based: Assignments 10%, Labs 20%, Tests 10% each for a total of 20%, exam 50%. If you do poorly on your assignments, we count 60% for the final exam and we don't count the assignment mark. If you do poorly on a Test, similarly we don't count it, adding 10% to the final exam maximum count (by rescaling it). Labs always count for a total of up to 20%, no matter how low the mark. There will be four labs. In fact, we add up a variety of possible marks, e.g. (10% ass, 10% T1, 10% T2, 50% exam), and (0% ass, 10% T1, 10% T2, 60% exam), and (0% ass, 0% T1, 10% T2, 70% exam), and (0% ass, 0% T2, 10% T1, 70% exam), and (0% ass, 0% T1, 0% T2, 80% exam), and we give you the maximum of the resulting set of marks, and then we add your total Lab mark, for an overall total %. Note that Lab marks always count. As a consequence of this, you cannot lose by sitting a Test, you can only gain marks, since a poor mark winds up not being counted towards your final grade. By the way, you can miss two assignments without penalty on the 10% that they attract towards the final grade. There will possibly be just 8 assignments on offer this year; if so then 6 satisfactory ones would get you the full 10% available. To be satisfactory, an assignment gets a mark of 40% or more, and is on time. If you miss more than two, the 10% is apportioned; eg doing three (out of six) satisfactory assignments would get 5% towards the final grade, half of the 10% available. Any assignments which are unsatisfactory due to having less than 40% will (if you need them) get a proportion of the full mark they would have got otherwise.## Videos Of Lectures

We record all lectures to video. To see videos of lectures, please go to Blackboard, select ENGR121, then select Vstream Videos on the top left-hand panel.## Syllabus

This schedule describes what we plan to cover during lectures in ENGR121.## Help Desk

The Mathematics Help Desk is a good place to come and ask questions if you are having trouble understanding tutorial and/or assignment questions, or material covered in lectures or in your extended reading. You are welcome here any time. Dr Howard Lukefahr is running a Workshop every Monday and Wednesday evening, 5-8pm in AM106 for all ENGR students.## Extra Help from Student Support
