I am emailing a link of this to everyone on the class list every week. If you are not receiving these emails or want to have them sent to another email address feel free to email me at jpmccarthymaths@gmail.com and I will add you to the mailing list.

Maple Catch Up
If you want to do Maple catch up, if for example you miss a lab, please download the Maple file from your email, do the exercises in Maple (either in a new worksheet or on top of the original file with the exercises), save the worksheet and email me the worksheet you were working on.
Week 8
We had our test on Linear Algebra first and then after a break we finished off the chapter on statistics and started talking about probability.
Week 9
We will do some statistics stuff in Maple and then we will delve further into probability.
Independent Learning: Exercices
You are supposed to be working outside of class and I am supposed to help you with this. Working outside of class means doing the exercises in the notes. Any work that is handed up will be corrected by me. Also you can ask me a question here on this site and I will answer it ASAP.
Questions that you can do at this point include:
- P.90, Q. 1-3 (these are particularly important)
- P.93, Q. 1-10 (these less so)
Maple Online & 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 the non-credit-course button 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, no go back to the Blackboard home page and click on the Maths Online button: it should be under an Academic Learning Support Tab. You can download Maple by selecting the Mathematical Software tab in the left hand column and following the instructions under the Maple item. Click Maple text to start.
If you have any problem with this take a print screen and send it to me and I will try and sort you out.
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!
Academic Learning Centre
Those in danger of failing need to use the Academic Learning Centre. As you can see from the timetable there is evening support. You will get best results if you come to the helpers there with specific questions.
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.
Additional Notes: E-Books
If you look in the module descriptor, you will see there is some suggested reading. Of course I think my notes are perfect but if you can look here, search for ‘Bird Higher Engineering’ you will see that the library have an E-Book resource.

Hello J.P.,
I was just looking at the questions on P93 that you recommended. I can’t seem to get my head around the second part of the questions from question 5 to 10. is there any chance you could give me a breakdown of one of them and I might then be able to attempt the rest myself.
Thanks.

Hi,
I will look at questions five and seven here.
Q.5 The first task is to pick two boys and the second task is to pick two girls. The number of ways of picking two boys from five boys is 5C2=10 and the number of ways of picking two girls from six girls is 6C2=15 so the answer is in fact (10)(15)=150 and not 60.
Q. 7 There are three tasks: pick the first digit, pick the second digit, pick the third digit. If the three digits are allowed to be repeated, there are five ways to do each of these so in total (5)(5)(5)=125 ways to pick a pin.
Regards,
J.P.

Hi,
Looking at just Q. 10 (b)… the first task is to place the first runner (8 ways), the second task is to place the second runner (7 ways), the third task is to place the third runner (6 ways), the fourth task is to place fourth runner (5 ways) and the last task is to place the last runner (4 ways).
Therefore, altogether, there are
(8)(7)(6)(5)(4)=6720 ways of placing the five runners.
Regards,
J.P.
