can somebody help me out? it's one of the first parts in number patterns I'm sure it's very basic but I can't wrap my head around it on the calculator, just say the pattern is triangle square circle, and then to find T10, it's says divide 10 by the number of terms (3) and I get 3, but in the example it says it's gets 3 with a remainder of 1 and then the answer is the first triangle ... like I don't understand the remainder bit !

you have to do it by long division! 3 doesn't go into 10 but it goes into 9 so you'd have a remainder of 1

Here's a hastily scrawled explanation :pac:

Isn't there a formula in the log book for this?

Say if there was a question on income tax or net income, would you need to know the rates of PRSI and USC?

BauBau19 · 06-06-2014 9:58am

How and what is everyone revising ? I've all the exam papers done. I'm just gonna do 2013 and 2012 again

Does anyone know if the chain rule is examined at ordinary level?

Badwulf · 06-06-2014 10:33am

Best advice I would give to people who are thinking of droping down on the day from higher to ordinary is too not do it. Even our teachers advise it, while our maths are a hell of a lot easier there are also a lot of maths that are not covered on the higher level course and will look really alien to you, this is according to my year head anyway.

Their level of maths would be much superior to ours though. I recently dropped down and I am finding it very manageable. I say if they really think there's no way of passing, there's no point in doing it.

Need help, when getting the roots of a complex equation using de moivres theorem.. I know that you put it in general polar form and if the equation is z^4 then you multiply the whole equation by 1/4 to get z. But what about the value for r? You multiply it by 1/4 too or do you use the inverse square root of 4 to get a different value for r?

Trouble with this maths is that its so hard to explain your situation! I hope I made some sense..

blueb · 06-06-2014 11:25am

i before e except after c

sylviaplath32 · 06-06-2014 11:29am

Somebody please help! Doing simultaneous equations and stuck on this:

2f + 2/3g + 1 = 0
f + 1/2 g + 1 = 0

What do I do with the fractions?

skippy1977 · 06-06-2014 11:32am

For the complex numbers you get the 4th root of r. You multiply the angle (including 2 pi n) by 1/4. Then sub in n=0, n=1, n=2, n=3

FatRat · 06-06-2014 11:32am

I get the complex roots thing now, spotted it in the book! So no need to reply

I'm no maths genius by any means but...
I think you put both equations over 6 as its the LCD of both fractions

So you're left with:
12f + 4g + 6 = 0
6f +3g + 6 = 0

Then you just treat it as a normal simultaneous equation.

is this on the ordinary course?! I can't find it anywhere in my book

caolan1996 · 06-06-2014 12:05pm

its higher i think
well i hope it is anyway

Saxo · 06-06-2014 12:22pm

Has anyone done the question in the exam papers about the wheat production and calculating how many hectares of wheat he can get etc, think its 2012 paper 1? might be wrong. fair confused with this question, hope something like it doesnt come up today.

The other explanation is wrong
you multiply the bottom line by -2
then you can cancel the f's
then treat it as a normal similtanois equation

if your still stuck theres a worked example in the marking scheme on examanationsdotie

Its sick, some of the questions expect you to work backwards all the time without giving you much information!

matthew the statue · 06-06-2014 12:37pm

Is there many just looking to pass? Im so scared that I will fail this ugh

Noccy_Mondy · 06-06-2014 1:25pm

Please guys, make sure you read each question carefully, and make sure that you are answering each question correctly - especially with this project maths, make sure that you answer what's being asked, it's easier to get sidetracked and confused with more writing on the page. With regards thinking you are going to fail - you won't if you try each question, don't leave anything blank, there are plenty of attempt marks to be gotten. Give a fair stab at every question. It's the first proper year of project maths, so my thinking is that the marking won't be too hard. Best of luck to ye all!

TheBoss11 · 06-06-2014 4:46pm

Paper was probably the easiest in years. Anyone else find it quite easy?

TaiHusky · 06-06-2014 4:49pm

That was fecking hard. I mean, what wis with the f:x question and the cardboard square one!?

Hollister11 · 06-06-2014 4:53pm

Horrible horrible paper

completely messed up!!

nimrod86 · 06-06-2014 5:01pm

Don't think I did well there at all...

I think I got all the financial maths ones mostly right, and then the rest I'll be hoping to scrape by on attempt marks

Did you use the Sn formula in the log tables? hadn't a clue about any of the functions

paper 2 will be even worse.

ye I used the Sn formula from the log tables and let a = 13 and d = -2 I think.. Ended up getting n = 25 in last part so I think it worked out okay

omara95 · 06-06-2014 5:06pm

Handy paper 1. Lets hope paper 2 is the same!

onethreefive · 06-06-2014 5:07pm

I can kiss goodbye to college now. Absolutely devastated. It feels like my life is ruined.

My lord I did so bad, I used 1 as the first term and 2 as the difference

thought it meant go from T1, T2, T3 etc. so frustrated

KellyR18 · 06-06-2014 5:11pm

I thought it was awful!!! It started off well then went horrible! The last question was fine but the middle was not the best. Can you repeat just maths on its own? I need a min of C3 for course and I don't think I'm gonna get?

Some colleges offer Special Maths Exams for people who didnt get their grade in the leaving cert, have you had a look at them? You'll probably be ok, they throw marks at you in ordinary maths for attempting and stuff

Buataisti · 06-06-2014 5:17pm

Fairly certain the final long question had a mistake printed. After asking you to differentiate it then asks for the maximum height of the rocket, which has already been given. I think it was supposed to ask for the maximum speed given the question prior to it.

Was the maximum height of the rocket 25m? I just read it from the graph but I'm not sure if there was a trick question in there.

I tried to use the Sn formula, but kept getting syntax errors on my calculator... ended up just writing as much as I could out and hoping for attempt marks

I thought it was a trick question and said 25m aswell!!

Badwulf · 06-06-2014 5:21pm

Do they really hand out attempt marks easily in O level? Because for the mocks I had a friend who had some pretty solid and valid attempts and he got 0 for them all

cferry3 · 06-06-2014 5:24pm

Such a easy paper, I'm still laughing at how easy that first question was :L

Yep, given how the question prior to the one asking the maximum height was to get the speed formula, and the one after the max height also used that formula it seems to have intended to ask for maximum speed, which basically means free marks for putting down 25 if i'm not mistaken.

typicalstudent · 06-06-2014 5:25pm

Anyone feel there were mistakes on the paper?
In the sequences in series question, in our Edco exam papers the recurring question is making a formula the sum of the first n series'. In today's exam it was the same question, but the usual way of just adapting the SN formula wouldn't work? Anyone else get this?

Also. In the final question it asks us to differentiate the height formula. The Dh/dt = 10-2t. This formula should give speed, but in the next question instead of asking for max speed it asks for max height AGAIN?

I think these are two of possibly a few mistakes on the paper. So they're guaranteed marks for you people worrying!

jazz101 · 06-06-2014 5:25pm

It was grand apart from the imaginary numbers, cardboard box and f:x stuff. That was hard as all hell. Especially the box. That "maximum size" thing annoys the hell out of me, always gone right over my head. Like couldn't I just say "h" is a thousand trillion and that would be the maximum size?

Aarong9224 · 06-06-2014 5:25pm

There was hardly any marks going for number patterns in that exam , 25 marks there is usually at least 50 sometimes 100 marks for it.
Anyone know what time the papers are posted on the examinations website ?

brijay · 06-06-2014 5:27pm

What did you guys get for the speed of the rocket ? Was it just distance divided by time? also what was the distance

jazz101 · 06-06-2014 5:27pm

Hmm, seems it wasn't just me who thought there was something up with the differentiation on the rocket question. It didn't make sense, the way they had put it.

Was just wondering the same thing. I need to add up the bare minimum marks I could of got and see if I passed. I am terrified I failed this paper.

Yeah im adding up my marks as well , im sure i didnt fail though need a c3 for college though.

Im sure you didnt fail , not many do at ordinary level.
