Question about the pythagoros therom question!

I got my answer as .34 or -1.34 and 'apparently' it's .37 or -1.37. I was .03 out so must have been an estimation error. Would I even be penalized for such a small error if it even is an error?

Probably. Did you round off early?

daisy17 · 06-06-2009 05:49PM

Make sure to go over statistics cuz I though i knew it for my mock and then had no idea how to do it! i completely blanked!

Think I must have done. So how many marks would ya loose just 1?

Irishgirl94x · 06-06-2009 06:30PM

Haha everyones talking about how many marks they will lose for certain things. I`m relying on attempt marks for maths. It was so bloody hard

I`m absolutely crap at maths and Paper 2 is my worst so I`ve failed it.

daisy17 · 06-06-2009 06:58PM

If anyone has the edco maths papers, the sample paper for 2003 in it, do you know where i can find the solutions? i know they're at the back but i don't know how to do the sum (paper 2 question 5 b) ... if you know could you explain it? thank you!!

swimminggurlX · 06-06-2009 07:43PM

I think you can get them on the internet at examinations.ie
Or just type in solutions to 2003 maths junior cert:D

Exams have been easy enough so far
English pp2 was confusingly asked for some things, maths was okay, hope the swimmming pool question was not worth too much.
I blanked in Irish p2. Could not believe it! Studied too hard:rolleyes:
Geography was eassy:o

evansmiley · 06-06-2009 07:44PM

i'm fairly sure this is it...(using sine rule)
15/sin120.69 = 9/sin|<rst|

15sin|<rst| = 9sin120.69

sin|<rst| = 9sin120.69 / 15

arcsin(or the inverse of sin)9sin120.69/15 = |<rst|

|<rst| = 31.061966667

|<srt| = 180-120.69-31.061966667
|<srt| = 28.2480333 = 28.25 degrees

what did everyone get for the q about soap in Q1 of Maths Paper 1

I seem to be the only one who got Brand A .. :S
I didn't use the part of the table that said how many bars there were because it said the price per GRAM ..
Is that right?

i did it twice and got brand a both times

You have your unit circle with sex and the city (sin, all, tan, cos).
In the sin quadrant, sin will be positive.
In the All quadrant, sin cos and tan are all positive
In the tan quadrant, tan will be positive
in the cos quadrant, cos will be positive.

If you get a question like tanA=-1,find the two values for A, go to your calculator and press tan^-1(1) and it will give you 45 degrees. This is your reference angle.
When you're trying to find any reference angle, don't put in the minus if its there eg don't say tan^-1(-1). You can't have a negative angle.

Now that you have your reference angle, you have to do something with it. Since the question told us that tan is negative, we go to the cos quadrant and the sin quadrant, because as I said earlier, in the tan and all quadrants tan is positive, so right now we ignore those ones.

To find the values:
In the sin quadrant, its 180-reference angle
In the all quadrant, its 0+ reference angle
In the tan quadrant, its 180+reference angle
In the cos quadrant , its 360- reference angle

so 360-45=315
and 180- 45=135.

Those are your two values for a.
If you were asked for the two values of sinA=-whatever, you'd go to cos and tan because thats where sin is negative. Same idea
If you were told sinA=+whatever, you'd go to all and sin, because thats where they're positive.

Hope that helped

ye thanks dat helped a load lol. i undastand it now tbh. sound

What did everyone think of maths.

partyatmygaff · 08-06-2009 12:36PM

Maths paper 2 was great. Not easy by any means but damn was it better than paper 1.

Only messed up about 1 part b and got a part c a bit messed up and I didnt complete the 2nd theorem.

Overall it was great, atleast a B now.

So relaxed now, nothing else worries me now

elaine93 · 08-06-2009 03:34PM

Didn't like paper 2 maths. Much preferred paper 1. I knew how to do the questions but i didn't have enough time to check over anything. My supervisor keeps reading the newspaper and it takes ages for me to get paper. :mad:

jumpguy · 08-06-2009 03:46PM

I preferred maths paper 1. I got a high B in paper 1 I'd say and a mid to low B in Paper 2.

CSPE was a dawdle.

cryto · 08-06-2009 03:48PM

stop cspe was so easy like. wpuld ya say der is anybody who didint get bono

Namlub · 08-06-2009 04:01PM

I actually found Maths Paper 2 quite easy, I've seen way harder ones in the exam papers. Still don't think I did brilliantly though, and I completely blanked on proving the triangle theorem but hey ho. CSPE was, well CSPE...

Eoin MurMur · 08-06-2009 04:07PM

I was happy with maths paper 2 despite a few big ish mistakes

CSPE was a joke :pac: Though some of my answers were a little silly and the people in my poster looked like eggs but I'd say I still got an A

daisy17 · 08-06-2009 04:15PM

I was pretty happy with Maths Paper II cuz my proofs worked out!

I really hope my ogive was okay though because the correct answers for them are always different from mine even though I've drawn it right, I just don't curve the graph at the right places!!

CSPE was all right - I found the question about the topics to do with the concepts quite hard to think of.

millington · 08-06-2009 04:26PM

Maths Paper 2 was OK. Still think I got at least a B if not an A.

CSPE was just stupid. Done the whole thing and looked over it 3 times in half an hour!

Tomebagel · 08-06-2009 04:34PM

lol cspe was funny i left at 2.00 and still answered everything very well and i still did all four Q's in section 2.

soccymonster · 08-06-2009 05:32PM

maths paper 2 wasn't as hard as i expected although i didnt get an A or anything, I think it could have just gave me the C that I want!:D

jclol · 08-06-2009 05:34PM

When i got the CSPE exam paper everyone was laughing... looked at page 1, saw Nelson... lol'd.

hacx · 08-06-2009 06:50PM

For the CSPE thing, last question, I did the CCTV thing.
I had two comitees:
The EQUIPMENT comitee, who got the bats.
The SMASHING comitee, who SMASHED the cctv cameras. Truth.

I finished with a ****in hour to spare.

What did you think of the exams?
