Maths Paper 1

Leaving Cert Student

Are there any nitty gritty pieces to learn off for this section that I have left out of this list does anyone know?

-Complex numbers equalities - de moivres thing where you show something like cos3x=2sinx+cosx for example!
-Integration of 3d objects
- first principles
- calculus proofs: product, quotient, chain.
- Differentiation by induction proof
- De moivres by induction proof


If anyone thinks of anything else at all please please please tell me, hoping to get the lucrative A in Project maths!

^ What do you mean by differentiation by induction proof?!

Leaving Cert Student

the thing where you actually prove the differentiation rule (ie. that you can bring the power down as a coefficient and reduce its power by 1) Its in the math book with the product rule, quotient rule and chain rule!

Oh i left out proof by contradiction

its the proof of the power rule:
If f(x) = x^n then df/dx = nx^n-1

And nope u seem to have most of the major stuff so u should be alright but u never know how the question will turn out on the day . Personally im just worried about financial maths ...wrecks my head its not the maths thats hard but just understanding what is asked of you. + i always seem to make mistakes on the time...:mad:

Yea I hate the ambiguity of financial maths too. If I make a mistake on say a part (a), does the examiner have to take my answer for part (b). In other words can I still get full marks on b,c,d,e etc.? In the mock this didn't seem to happen, worryingly. There aren't any financial maths proofs or anything are there?

The mock marking schemes aren't adjusted like the real thing will be when everyone does ****e in the question. Like in the project school marking schemes in 2011, parts (a), (b) and (c) of the financial maths question were worth 40/50 in the end up, and (d) and (e) were only worth 10/50.

They're desparate for people to get higher grades so if you do make a wee mistake you should be grand!

Is that not paper 2?

It can be. I know the proof of irrationality is more paper 1-ish though, its in book 1 too...

It's in my book 2 so I'd say that's irrelevant. A proof by contradiction question came up on a SEC Paper 2 so just from that I'd say its probably paper 2

Oh I thought that was just an edco sample paper, my bad, must be paper 2 so!

My grinds teacher said that proof by contradiction can come up in either papers.

Don't forget about Financial maths and Logs.

How's everyone getting on in the Sample papers?

I did the 2013 Sample Paper 1 today. Timed myself and did it in exam conditions. I did horrible. Far worse than i normally do. God, That Puzzle question...

I did well on the 2011 Pilot school Paper 1 but I'm thinking they made the Pilot Papers far easier for the pilot schools to show that Project Bull**** works

Sorry for being off topic but didn't know where to ask. On paper 2 on question 6 if I learn how to do all of the constructions would I be relatively safe?

you should do theorems 11,12&13 too

I'm in a Pilot School and everyone found the Paper One last year really difficult. But yeah, the marking scheme was massively adjusted, I only answered two parts of one of the long questions last year and got most of the marks.

My attempts at the sample papers are so bad it's not even funny any more. I didn't even know where to start with that jigsaw question. Or last year's one with the robotic arm thingy.

Although it could be something to do with the fact that I've given up even trying to revise the chapters and just decided I'd plough straight into the papers themselves. Needless to say, me and maths aren't on good terms.

Cheers, so those 3 and the constructions and I'll be covered?

Not necessarily. I dont think they HAVE to ask a construction or Theorem for Q. 6. I think they can just ask for a proof given a situation

I'd be lost completely then, is it not usually construction and theorem as the part A and B?

They can give you a shape and you've to work on it somehow too, I think on last year's paper there was something to do with an incircle, as well as the 60 degree angle construction. I know 6B is the crazy shape but in 6A they can ask you something too, based on the theorems you're meant to learn (not to prove, there's 22 in total you're meant to be able to apply).

Do we have a choice of Calculus questions on our paper? There was a choice on the 2011 past paper but none on the 2013 sample paper

no choice

Wouldnt it be a lovely surprise if they decided to give basically the exact same questions as on the sample papers with just different digits? Then I might get my 38%..
Im in way over my head with this, I dont know where to turn or focus
