OMG! 3 theorms!!!

challengemaster

f'k sake i almost died when i saw we had 3 theorms on the paper:eek: , luckily i knew them;) but i was surprised, first time ever. also...i now hate triangles and never want to see one again. too....many....triangles! <pull hair out>:mad:

oRlyYaRly

1/6 of the paper was theorems. Easy marks!

Easy marks if you knew them. I fecked up pythagoras's one, could only do half of it. And I constructed a triangle for the first time EVER in the exam, made up half the answers, drew scale models to work out problems (like that damn river question, I mean wtf?).....basically, I think I failed. But I'm not sad about it because I was thinking about it, and I don't think I'm getting below a C altogether because of my paper one!! Yayage!! Then I spent the break ripping up maths papers because

I SHALL NEV0R HAVE TO DO HONOURS MATHS EVER AGAIN!!!!!

At least TRY and do honours Leaving Cert! :eek:

In fairness, they were three easy ones BAR Pythag. but it was stressed enough thatit was comming up

What way do you do Phythagros? The one in our book is outrageously stupid but our teacher told us a very easy way.

Split the triangle into two triangles, look for similarity between the big one and the lil ones, then cross multiply etc. There is an easier way involving squares though, I'm not sure of it

I'm too damn crap! And I think I'm also going to be doing 8 other subjects, and I'd need to devote so much time to maths that I won't have....NOT looking forward to doing that many exams, but don't want to give any of them up either!

now i never said they weren't easy ofc i got them all done fine,stayed up until past 1am studying them getting them drilled in. even pythagoras was frekin easy.

Easiest maths paper 2 ever!Delighted with it.I can guarantee that loads of people found the total surface area of the steamroller instead of the area of the rectangle.;) I also have to say thanks to BMH for the Rate Of Flow question.Thanks buddy!:D

? Suppose you mean instead of the CSA

Sipefree

Woot. My maths teacher was right. Pythag's theorem did come up. Luckily I had memorized it the day before.

I actually think I did really well in that one. I answered them all and I think I got it all right. I wrote my final answers into the question paper so I can check it later.

I won't know until September though.

Piste

This morning I decided to look over the theorems, I noticed that the parallelogram theorem hadn't come up yet so it probably would this year, so that and the pythagoras one were the only two I learned- and they both came up The other one was just common sense really and I could answer on it. But there were some very nasty questions on that paper, question one in particular was not nice at all, and parts of question three and four I had to look at a few times before I realised what to do, and even then a lot of what I did was guesswork. But at least I managed to answer everything

Jello

Went pretty well for me...could do all the theorems and even Trigonometry!!
Which I usually suck at!
But I couldn't do the thing about the sand in the egg-timer.

Heh, no problem. Ironically enough, it was the only place I know I made a mistake in. I forgot to divide the volume by two but I'll probably only lose a mark or two because of that.

Easy enough paper really, I'm glad there were so many theorems.
Now to find the million mistakes I mde that I don't know about yet...

Piste

My shiney new compass kept being non-accurate. And my incircle didn't touch the bottom of the triangle. Yep no (or at least very few) marks for Pistey.

BMH

Meh, my incircle was off at every side, I just set it in such a place that it wasn't too obvious, and shaded the lines close to the triangle so that it looked like it touched.You'll get the marks for the method, don't worry.

Piste

Just draw it, and leave the construction lines to show we knew what we were doing.

oRlyYaRly

If it touched off two sides and was just a little tiny half of a millimeter off one of the sides, can you still get 10 marks?

Piste

mmm probably 8/9. Anywho, you'd probably get marks for having the triangle drawn properly, and then only a few more marks for the incircle.

BLARG

I got the first 2, but on pythagoras, I just proived they were congruent, then drew a blank.

Piste

My second last line was something like |ac|^2+|ab|^2=|bc||bc|+|bd||bc|

and then I kinda just "lost" the |bd|bc| and skipped ahead to |bc|^2=|ac|^2+|ab|^2

So hopefully they wont look to closely >.>

Do they follow your work all the way through or do they just give marks for the correct answer and only look at your work if you got the wrong answer and they want to give you attempt marks?

Obviously not for theorems and such.

BMH

They allow 2mm grace for incircle and other constructions. You'll be fine.

yourpetzombie

I got home and realised I constucted my incircle inside a different circle, not the first one I constructed.

And those theorems were practically free points.

That paper was like the easiest paper two ever. It didn't require any thought at all.

Anyone know anything about the solutions being put on the 2fm website or something??if u do could you please post a direct link 2 that page!thanks a million

Heh, I didn't know how to do the in-circle thing at all so I just spent a few minutes trying to find the right spot so that'd it'd work and put in sneakeh construction lines afterwards :P

disney

My incircle was out by the tinyist little mm, but i wud b damned if i left the bitch!!!!
I made a heavy line on the outside of the triangle, and hey presto it looked alright!!!!

Can sum1 tell me the answer to the rate of flow question:rolleyes:

BMH

180 seconds.

Haha, I did that in the mocks and got full marks.
But I had a few construction lines.

ANarcho-Munk

I only got one of the theorems right though, i might have gotten the triangle one right as well but i'm not sure. I was looking at Phytagoras theorem last night but just went "Ah bollocks, i'll do it tomorrow".

Typical me.

lilmissprincess

Yes!!! I got the flow thing right, I rounded it to 3 minutes...
Thank God, i got something right. I bulled my way through Pythagforas, remembered half of it, then solved my own to show how its done...hehe..
That steamthingy was impossible, i was in massive thousands of numbers!!

The exact same thing happened to me too!:eek: I wonder why that happens though? It should work in both cm and m I would have thought???

BMH

Ah, but 100cm^2 doesn't equal 1m^2
10,000cm^2 = 1m^2

kwiva-g

Ya that makes sence but that wasn't in the question I don't think? Anyway I'm sure what you just said must be the reason!

Piste

For the roller thing I got 138%. Yes 138%

Then for rate of flow I got 720 seconds.

Yeah no good grade for Pistey.

Jello

Didn't even do the rate of flow question and got 28% (i think) for the roller yoke.

oRlyYaRly

i got 360 seconds and 3.something percent.

JC06

I got 3. something percent aswell.It was like 3.82% but I hadnt a clue how to do it...

BMH

3.75% and 360 seconds. But after the exam I realised that it asked for half the volume, whilst I did all the volume. so the right answer according to everyone else in my class is 180 seconds.

Thats what I done, ah sure we'll get 1/2 marks anyway!

By the way 40% of our paper was geometry, according to the radio. ARRRRGGGHHH!!!!!!!!!!!! I hate geometry:eek:

Nanaki

*sigh* I didn;t get the theorem of pyth. but I got the other two okay...

7/10 for 360, I'd imagine. 3 pts lost for 1 incorrect step, not dividing by 2.

BMH

Judging by the marking schemes at examinations.ie, it would be a "Blunder" which only costs one mark. They really throw marks at you to make up for no choices in the exam.

your attitude to maths is very similar to mine. I managed to scrape a C in the mock and then got a D in the JC and then I noticed that LC Ordinary is still hard.... I've picked pass for next year (going into 5th year) as I wouldn't even be close to being able to do Honours
