Continuous Assessment
You are identified by the last four digits of your student number unless you are winning the league. The individual quiz marks are out of 2.5 percentage points. Your best eight quizzes go to the 20% mark for quizzes. The R % column is your running percentage (for best eight quizzes — now this includes missed quizzes — before I was doing the best non-zero but now I am including the zeros if a zero is in your best eight), MPP is your Maple Percentage Points for the biweekly lab, MT your mark on the Maple Test and MM your Maple Marks (as a percentage). GPP is your Gross Percentage Points (for best eight quizzes and Maple). Most of the columns are rounded but column 11, for quiz ten, is correct — as is GPP.
The Maple Test went very poorly… I have sent ye on worked solutions — please see the Remarks therein.

Any students who missed a Maple lab are invited to do the relevant lab in their own time and send their Maple file to me via email but this has to be completed before the class of Wednesday 6 May.
Quiz 11 Question Bank
This question bank is MASSIVE… and I am quite happy with that. I count on P.119/120 there are 17 questions but only seven ‘types’. The two questions on P.138 are similar. I am happy because I want ye to learn and understand the general idea/technique from a few questions rather than learning off set questions (which in fairness the majority of ye are not doing).
- P. 119/120, Q.4-6, 7 (iii)-(x), 8 (e)-(j)
- P. 138, Q. 1*, 2*
*good example on the bottom of page 147
There is no value in writing down the final answers alone — you will receive marks for full and correct solutions — but nothing for final answers without justification or skipping important steps. Please don’t learn off model solutions — you need to understand the material not just on a superficial level to do well later on. Quiz 11 runs from 19:00 to 19:15 sharp on Wednesday 6 May as it is not a ‘Maple’ night.
Week 11
We did another inverse Laplace transform that required a completing of the square. In the last section we had six examples of full Laplace Transform questions — we got through three and started a fourth
Week 12
In Week 12 we will finish off the last three examples. Then we will talk about applications — especially to damped harmonic oscillators. If we have extra time left over I will take questions from the class and invite you to do exercises if we run out of exercises.
Week 13
In Week 13 we will go over the exam paper after p.152. We haven’t done Q.1(a) and 2(c) in the same way so I will have alternative questions. I am not going to ask you questions like Q. 1 (d) (ii) and 4. (a) (ii) but I will have alternatives.
Academic Learning Centre
The word on the Academic Learning Centre is that although the evening session perhaps might have been made exclusive to evening students, the fact of the matter is that they are not.
My departmental head suggested that if a group of ye want to get an improvement in your ALC experience, that ye should email questions to catherine.palmer@cit.ie in advance of the session. Dr Palmer said that this will allow her to more easily help ye.
Study
Please feel free to ask me questions about the exercises via email or even better on this webpage. Anyone can give me exercises they have done and I will correct them. I also advise that you visit the Academic Learning Centre.
Continuous Assessment
The Continuous Assessment is broken into Weekly Quizzes (20%) and Maple (10%). There will be eleven weekly quizzes and your eight best results will count (so 2.5% per quiz from eight quizzes). You will receive an email (i.e. this one) on Thursday/Friday detailing the examinable exercises. Maple consists of five labs and a Maple Test in the sixth lab. Satisfactory participation in labs gives you 1.5% and the Maple Test is worth 2.5%. More on this in the coming days.

Hi J.P.,
I’m just wondering if I’m going down the right road with the first three parts of questions i have send you (iii),(iv),(v).
I am stuck on the (vi) one; I know you’re under pressure , so no panic if you don’t get back to me tomorrow.

Part (iii) is perfect.
With part (iv)
is correct and you are good down to
After this (and with the other questions), you made some silly mistakes… you must have been tired.
You need to add
to both sides to get
For part (v) you are correct down to
It is
not
so you should have
Similarly for
you should get down to
. You got
correct.
Part (vi) is perfect so far.
Regards,
J.P.

Hi J.P.,
Was just wondering about Q. 8 (j) on page 121; I’m a bit stuck. If you could help us that would be great.
Thanks.

Our first thought is that this is not in the tables so could we write it as a sum of simpler terms that might be in the tables… PARTIAL FRACTIONS.
First thing to do is factorise the denominator.
This is two Rule Is so we may use the Cover Up Method:
Now we apply the Inverse Transform to find
