****Leaving Certificate: Higher Level Maths Discussion****

plmko

So excited for Maths! What's the buzz with ye?

Huell

Cant wait for it hopefully they will be nice to us since its he first full year of PM

yohan the great

Very very scared

plmko

I think it will be harder than last year but not half as hard as 2011/2012! Thank
god!
I wonder what they'all base the Context and Applications questions on?!

FatRat

In context and application I'm expecting a financial maths question, an exponential function/logs question and some sort of calculus question, probably integration orientated.

First 6 questions are fairly obvious.

cggreene

going to go over complex Numbers and financial maths. It's not gonna be good

LC.student2014

I have no idea how to do Rates of Change questions, anyone that could help?

Ah I'd love a Financial Maths long question!

Want=GivenxNeed

Hotale.com

Anyone else done nothing for it? Keeping on Geography was a terrible idea.

LC.student2014

I dont really get it want= given + need? how does that work?

peekachoo

Geography and maths together needs to be rescheduled.

JDOC1996

So what do we actually need to know/prove for paper 1?

LC.student2014

Need to know how to construct surd2 and surd3 and prove surd2 is irrational is it?

That's all I've learned, and how to get the average value of a function too.. Is that it?

Calvin

I had a 7hr maths course on paper 1 last Sunday. Hoping that pays off! Also have geography in the morning.....never good

@LCStudent2014

Want (what you're looking for) = Given (given in question in written terms so you have to change it to maths terms) multiplied by Need (construct this from the two other parts) kind of hard to explain on this sorry!

Amortisation Formula, De Moivres Theorem for all n is an element of N also.

plmko

Hope we get to construct square root two, handy few marks

What do you mean the average value of a function?

Isn't that in the log tables?

The contrast between the 2013 and 2011/12 papers is ridiculous. It would be amazing if it was like last years, but I'm expecting pure filth tomorrow..

How do you prove root 2 is irrational?

Proof by contradiction

Flickka

Does anyone know if that formula for average value of a function is in the log tables? Also in the 2011 papers, in the question on integration, is that type of question still on the course where you have to make some type of substitution and change the limits etc? I haven't been able to find any reference to it in any of the maths books...
Thanks guys!

Missovoxo

Oh gosh I need a B in maths and it don't think it'll happen tomorrow!

Shane15

What would be the most important things to study if you were literally trying to at least pass?

Financial maths! the funny thing is I want to be an Accountant but I suck at it!

I definitely need to look over this, thanks. :P I used to be so good at maths, I don't know what happened LOL.

And complex numbers, and the root of a function and differentiation/integration.

Common sense stuff that should come up would be simultaneous equations, -b formula stuff like that!Fingers crossed!

Thanks, and yeah I love simultaneous equations haha.

Who's thinking induction will show its face?

Ciaran8

Any advice on what to practice tonight before tomorrow, getting worried ima fail and don't fancy repeating! Any help at all please

Definitely, it was on the sample and I don't think it was on last year. I can't get my head around it though!! Hopefully we can get most marks for doing step 1, 2 and 4.

feckin priests

The basics of everything, like financial maths, logs, diff and int.. Maybe induction and root 2 formula

XtotheZ

can compound angles come up tomorrow?

K6Y

Btw, what paper 2 content can possibly come up tomorrow?

peanut.lover22

Do you think standard deviation and z-scores are gonna come up?

mabye not tomorrow but it deffo will be up

So hi, kind of sorry I had a look here today but too late now.
Anyway fancy explaining how to get a) The Root of a Function and b) The Average Value of a Function? You'd be sound.

what do you mean by root of a function?

avg value in integration is 1^(b-a) and then the integration part with B the larger of the two values. ie On the integral symbol it is the higher of the two numbers

YouTube is the best for this kind of stuff.

XtotheZ

I literally seen it for the first time two days ago, very easy but if you didnt know it and it came up it could cost ya a mark or two. Sorry, my explanation wasnt exactly great

Janeh9

Jesus I've done nothing all year I was lucky in the mocks that I even passed got a D3 in paper 1 and a D1 in paper 2 I'm only sitting the honours for the extra 25 I have no idea what to study :P

LC.student2014

So all you need to know really besides common sense is constructing surd 2 and 3, proving surd2 is irrational and the average value of a function, oui?

Nope, integration by substitution is removed. I know because now in the applied maths course they will give you the answer to an integration by substitution in order to complete the question, whereas in previous years (pre 2012 I think) you had to work that out yourself.

Shane15

If you're asked to use De Moivre's Theorem to solve the equation (insert real number + imaginary number here), does n automatically = 10?

Chonaic17

Does anyone know what the story is with Binomial theorem, can it possibly come up, or is it only on for the 2015 syllabus onwards...

Daithi MacG

Im about 95% sure binomial theorem is NOT on the course this year.

Daniel2590

If binomial expansion and binomial theorem are the same thing, you need to know how to do it...
