• The first piece of advice is to read questions carefully. Don’t glance at a question and go off writing: take a moment to understand what you have been asked to do.
• Don’t use tippex; instead draw a simple line(s) through work that you think is incorrect.
• For equations, check your solution by substituting your solution into the original equation. If your answer is wrong and you know it is wrong: write that on your script.

If you do have time at the end of the exam, go through each of your answers and ask yourself:

2. does my answer make sense?
3. check your answer (e.g. differentiate/antidifferentiate an antiderivative/derivative, substitute your solution into equations, check your answer against a rough estimate, or what a picture is telling you, etc)

## CA Results…

with comments, should be emailed to you this week. Test 2 Marking Scheme here.

## Week 12

We had some tutorial time from 18:00 – 19:00 before the test for those who could make it.

We then looked at sections 4.2 (completing the square) and 4.3 (work).

We did not have time to complete Example 4 on p.171, nor section 4.4.2 (centre of gravity of solid).

Both what we did in class and what we didn’t have time for can be found here.

## Homework

If you want to do some work on Chapter 4, Further Integration before starting more general revision you could look at:

• P. 161, Q. 1-15 (revision of integration)
• P. 167, Q. 1-5 (integration by parts)
• P. 173, Q. 3-7 (complete the square — $\arcsin=\sin^{-1}$ and similarly $\arctan=\tan^{-1}$)
• P. 176, Q. 1-3 (work)
• P. 182, Q. 1-3 (centroids of 2D laminas)

## Week 13

There is an exam paper (Winter 2018) at the back of your notes — I will go through this on the board from 19:00-22:00 Tuesday night.

Past exam papers (MATH6040 runs in Semester 1 and Semester 2) may be found here.

Recall that this module is MATH6040: Technological Maths 201 and not MATH6015: Technological Maths 2.
