Test 1

Results pending.

Course Notes

At the moment they look like here.

Week 6

In Week 6 we began our study of beam analysis.

Week 7

In Week 7 we will continue our work on beam analysis and indeed look at Macauley’s Method. When we finish the beams we will do two more examples of non-homogenous ordinary second order linear differential equations with boundary/initial conditions.

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 question by yours discussing the Delta Function \delta(x)?

Test 1

I have the test results. I will bring the tests with me to the next two tutorials: one of which you will attend.

The below is a scatter graph of Test 1 scores vs missed days. The correlation is strong and a statistician would call the effect of missed days on your test score to be large. Of course this doesn’t surprise me in the least. The fitted line says roughly that the average test score is given by T(d)=77-4d where d is the number of days missed. In other words: missing seven lectures and tutorials means that your score is nearly 30 percentage points lower than what it would have been had you had perfect attendance.

Test 1

The first 15% test has been POSTPONED and now will take place at 4 pm Monday 21 October in B263 (Week 6). You can find a sample in the course notes, after the section on rates of change I think. It is a test that could arguably take 42 minutes but I’ll give ye from 9.05 — 10 am. You will be given a copy of these tables. Don’t worry I’ll scribble out the “UCC”!

Note that the format will be the same of this.

  1. Differentiation from First Principles
  2. Tangent Lines
  3. Differentiate by Rule
  4. Differentiate by Rule
  5. Differentiate by Rule
  6. Rates of Change
  7. Rate of Change/ Geometry of Graph

Test 1

The first 15% test will take place at 5 pm this Thursday 24 October in B228 (Week 6). You can find a sample here. It is a test that could arguably take 40 minutes but I’ll give ye from 17:05 — 18:00. You will be given a copy of these tables. Don’t worry I’ll scribble out the “UCC”!

Note that the format will be the same of the sample:

  1. Maclaurin Series OR Taylor Series (Taylor Series formula given)
  2. Error Analysis
  3. Taylor Series of Several Variables (formula given)
  4. Euler\Three Term Taylor Method (Three Term Taylor Formula given)
  5. Homogenous Second Order Ordinary Linear Differential Equations

Note that I like to make the sample harder than the test and the Q. 1 on the sample is a bit of a dinger alright!

At the moment they look like this.

Week 5

In Week 5 we study of second order ordinary linear differential equations.

Week 6

In Week 6 we will do two more examples of non-homogenous ordinary second order linear differential equations with boundary/initial conditions. Then we will move onto beam analysis.

Attendance

Frankly, as a group our attendance is abysmal. Not coming to tutorials and regularly missing lectures only means one thing: failure. Attending everything does not guarantee success but it is certainly necessary. You will not be getting much sympathy from me if you fail the test miserably having not attended class properly.

Test 1

The first 15% test will take place at 9 am FRIDAY 18 October in PF45 (Week 5). You can find a sample in the course notes, after the section on rates of change I think. It is a test that could arguably take 42 minutes but I’ll give ye from 9.05 — 10 am. You will be given a copy of these tables.

  7. Rate of Change/ Geometry of Graph

Course Notes

The notes contain all the lecture material, all the exercises and exercise sheets as well as all of last year’s assessments and you will need them from Monday on. They cost €12 and are on sale in the copying centre. Also find a useful reference here.

Week 4

In Week 4 we worked on the Chain Rule and spoke applications of differentiation to rates of change. Finally we started talking about the duality between algebra & geometry.

Week 5

In Week 5 we will continue our work on the interplay between geometry & algebra and learn how to find the maxima/minima of functions.

Tutorials

Regarding the tutorial time split:

 BioEng:
  – If you are finished early on Tuesday your tutorial is Friday at 09:00 in PF45.
 – If you are ‘finished’ at 16:30 on Tuesday your tutorial is Thursday at 17:00 in PF45
Building Services:
  – You can come to the Friday 09:00 tutorial as well as/instead of the Tuesday 17:00 if you wish to do so.

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.

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

Week 5

In Week 5 we will do frequency distributions and begin a new chapter with indices.

Assessment 1 Results

Assessment 1 Results are on your Blackboard right now. Question five (about the reduction in area) has been declared null and void so everybody is being awarded that mark.
