## Continuous Assessment Marks

I will send you an email either today or Monday regarding your continuous assessment marks.

## Week 12

We finished the quick section on mean and root-mean-square values and then we spoke about differential equations.

## Week 13 – Revision

- Tuesday 09:00 in B149
- Thursday 09:00 in B180
- Thursday 11:00 in B188

Sadly you have lost out on a tutorial and an extra revision class due to the test you have on Week 13.

The review will be given over to going over last year’s paper (at the back of your notes). If the paper is completed I will take questions from the class. If there are no questions I will help one-to-one.

## Study

Please feel free to ask me questions about the exercises via email or even better on this webpage.

## Student Resources

Please see the Student Resources tab on the top of this page for information on the Academic Learning Centre, etc.

StudentHi,

Need some help with Winter 2014 Q. 3(a) iii.

J.P. McCarthyI will say that this was a particularly nasty question… the fact that it is an integral on top of the fact that we can’t easily use the ‘cheat’:

… and I suppose no help with the factorisation also

The following should answer your question:

Your partial fraction expansion is correct and the integral is equal to:

.

The first anti-derivative is easy because it is a : the -substitution will yield:

.

The second term is more troublesome. The marking scheme does the substitution… here I show how to do what you are trying to do properly…

Taking

.

This is not equal to

.

Looking at :

.

Therefore we can say

via the ‘cheat’.

I hope this answers your question. Your question won’t be an integral.

Regards,

J.P.
