## Week 1

In week one we showed that differential equations can arise in engineering. We discussed how some differential equations do not submit easily to analysis and that sometimes we would have to find approximate solutions. We then proceeds to review of calculus. Finally we answered the question of how calculators work by developing a theory of power series.

## Tutorials

Tutorials start properly this week. Ted should have a division of the class such that one group this week is Thursday 16:00 while the other is 17:00.

## Academic Learning Centre

I would urge anyone having any problems with material that isn’t being addressed in the tutorials to use the Academic Learning Centre. As you can see the timetable is quite generous. You will get best results if you come to the helpers there with *specific *questions. You could also win a tablet device if you enter a competition that they are running.

## Week 2

In Week 2 we will review partial differentiation and have a look at two-variable Taylor Series.

## Test 1

Test 1 will be on the Thursday of Week 6. Expect a sample in Week 5.

## Study

Please feel free to ask me questions about the exercises via email or even better on this webpage — especially those of us who struggled in the test.

## Math.Stack Exchange

If you find yourself stuck and for some reason feel unable to ask me the question you could do worse than go to the excellent site math.stackexchange.com. If you are nice and polite, and show due deference to these principles you will find that your questions are answered promptly. For example this question addressing the strange conclusion that the Maclaurin Series of !

## Calculators

Please note the following taken from the CIT code of conduct for CIT examination candidates:

“*Where a pocket calculator is used it must be silent, self-powered and non-programmable. *

*It may not be passed from one candidate to another. Instructions for its use may not be *

*brought into the Examination Hall. *

*The term ‘programmable’ includes any calculator that is capable of storing a sequence of *

*keystrokes that can be retrieved after the calculator is turned off or powers itself off. Note that the *

*capacity to recall, edit and replay previously executed calculations does not render a calculator *

*programmable, provided that this replay memory is automatically cleared when the calculator is *

*powered off. Also, the facility to store numbers in one or more memory locations does not render *

*a calculator programmable. *

*Calculators with any of the following mathematical features are prohibited: *

*• Graph plotting *

*• Equation solving *

*• Symbolic algebraic manipulation *

**• Numerical integration**

*• Numerical differentiation *

*• Matrix calculations *

*Calculators with any of the following features are prohibited *

*• Data Banks *

*• Dictionaries *

*• Language translators *

*• Text retrieval *

*• Capability of remote communication*“
