## 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.

## 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 superb answer dealing with what we did on Tuesday & Wednesday.

## Maple & Wolfram Alpha

If you are subscribed to CIT MathsOnline you will have free access to the mathematical software package *Maple:*

**Self-enrolment for Maths Online**

1. Log into Blackboard Learn

2. Click on the Courses tab button at the top of the screen. Go to Course Search and type Maths Online in the box.

3. Once you’ve found the course, click on the action link button next to the course and click on Enrol. This should take you to the Self Enrolment page.

4. Your Access Code is mathsonline (lower case, no spaces).

5. After you’ve finished click Submit. You should now see a message that says your enrolment was successful.

Once you’ve enrolled, you can download Maple by selecting the *Mathematical Software* tab in the left hand column and following the instructions under the Maple item.

I myself am not a *Maple *expert but ‘grew up’ with another mathematical software package *Mathematica*. *Mathematica *powers the “computational knowledge engine” WolframAlpha. Go on ask it a question!

J.P. McCarthyYou got Q.8 wrong.

“A rectangular box has a square cross section of side and height . If the side is increased by 2% and the height is decreased by 1%. the change in the volume of the box is what?”

You chose (c) 6%. I had a look at your paper and what you did is looked at , however the height was decreased rather than increased. Therefore we should have looked at for an approximate increase of (b) 3%.

Regards,

J.P.
