SYLLABUS

The syllabus for this semester includes


1. What am I doing and when? Answer.
2. A more detailed account of the order in which subtopics appear.
3. The official detailed syllabus is here, but things have evolved a little since that document was drafted. It needs a bit of an upgrade and that will be happening for next year, 23/24.

This unit is assessed 100% by examination only. There is no coursework element.


RESOURCES

Main University webpage for students.

Mech Eng info for students (Moodle) (You'll need to type your userid and password).

There is a Maths and Stats Resource Centre at the University of Bath. Called MASH, it operates drop-in sessions at various times.
In addition, there are further online resources at the Mathcentre website.


MISCELLANEOUS

Greek letters. Don't get your etas, zetas and xis mixed up. Nor your phis and psis. And meet your first discontinuous letter.
If you want hints on pronunciation depending on where you are in the world, then this is the place.

SI prefixes and strange units of measurement.

Table of integrals.

History of the trigonometric functions.

Information on the hyperbola including where the name came from.

Why I am smug, what I don't expect in class, and I'm not sure that I believe this.

If it ever seems like this in a lecture, then you need to give me a good kicking!

Maths teaching in the past. Dodgy examples of exam/coursework submissions.

L'Hôpital's rule - the musical. (This isn't NSFW but....turn down the volume first!)

This is why your maths must be correct.

COURSE NOTES

These are meant to assist in your understanding of the various topics in the syllabus. If there is anything you didn't understand in the lectures, look it up here, and you won't be hindered by the remnants of a Welsh accent. Alternatively, you may wish to check out what I am about to do in the next lecture. Most of the examples presented in these printed notes are different from the ones given in the lectures so these may also be of some use.

The full set of notes is here.

UNIVERSITY CALCULATOR

The University will be supplying calculators for the Mathematics exams. Currently (i.e. September 2018) the designated species is the Casio FX-85ES. Further information on functionality may be found here.


TEXTBOOKS.

Essentially anything with the words "Engineering Mathematics" in the title is likely to be sound. So Glyn James, Stroud, Kreyszig, Croft and Davidson, Kuldeep Singh are all excellent.

Beware of the word "Advanced", as in "Advanced Engineering Mathematics" because some of these are seriously advanced. So check the contents pages. In fact, in book titles, the word "Elementary" doesn't always accord with the standard dictionary definition, and occasionally "An Introduction to..." requires you to have gained a PhD prior to even contemplating the merest possibility of looking inside the cover. So always check the index first. You've been warned.

HOWEVER, my advice is to check out some of these books in the Library prior to purchasing anything. Some people get on with Stroud but hate Croft, for example, whereas others feel precisely the opposite. Always check prices on amazon.co.uk.

You will generally find that textbooks have little to say about curve-sketching.
