** Higher Level Maths Paper 1 2012 Before/After **

Happy with that MUCH easier than last year.
Completely forgot how to do the differentiation from first principles but its the only thing i couldn't do..

Anyone else get question 8 part c out? just wondering if I got it right.

Thank you...but we were taught a very different formula for the general term.

Ooops sorry, I skipped a few lines. That is derived from the formula, but you just isolate the x by using the indice rules

Oh ok, thank you. I think I can see now where I went wrong, hopefully won't cost me many marks.

I think i got 2k(root3) all over three or something for integration part c...no idea if its right, just kept going til I arrived at something!

Same here how did you show that there was no term independent of x ?

I just worked out the expansion and showed that all the values had an x beside them. I have no idea if that's right or not though.

We all seem to have got something with a root k in it so I'd say we were all reasonably close

Yeah exactly, hopefully it will only be a blunder or 2 and we still end up with 15 or so out of 20

Dunno where the idea of Q4 being easy came from. I was so good at it, one of my best q's, and I couldnt f*cking do any of it.

Wait, was 1 (b) the factor theorem?! I never really did that 'cause it came up last year, I managed to answer it right though!

Where?

You know for question 6 b (ii)? I got the equation of the tangent for the positive value of root9. I had a feeling that would be right but I also did it out for the negative value as well because I wasn't really sure. Do you reckon it'd cost me marks?

Might be a blunder, not too sure.

*Says it was soo easy.. does shít.

Please stop, it was a difficult exam, maths in general is extremely difficult. If you're going to call a leaving cert maths exam easy you best back it up with an A1 grade which by the looks of things you haven't.

Well done to all the tweeps who did well, no doubt through all the hard work paid off

I actually thought it was a very difficult paper and was quite disappointed with it. As a couple of people said (thanks guys) I was just talking about one question, which I didn't do in the exam.

I think I did get an A1 on that paper by the way, between 91 and 93% I'm estimating. But I feel paper 2 will drag me down, so yes I probably will do shít overall, thanks for backing me up on that.

leaveiton

Yeah that's what I thought. Grr, and I was going to leave it the way it was. Oh well, don't think it'll affect the actual grade I think I got.

I don't know how weak your paper 2 is but it's a bit much to imply that anything below an A1 is shít.

in q8 b(i) i got 4ln7 and multiplied it in gettin ln28. is this wrong??

DepoProvera

Bahhh... Just went through the solutions and I made some silly damn errors.. Concentrated too much on the c's and got some a's wrong.. Estimate 88% before attempt marks.. blah integrated e^3x to 3e^3x....

I started to read that but then I realized that you're a girl so your argument is invalid

Spattersonox

I was pleased with this exam. If you wanted an A1 i'm sure it was really difficult, but I want a C so I'm happy with it

Awhh mannnn.... it's ln7^4!!! -1 for slip I'd say

Yeah cos it ln7^4 not ln7x4! Only a slip probably?

Do you reckon leaving it as 4ln(7) will be a slip or blunder or will they accept it as full marks?

As in, it's probably going to drag me down to a B, and maths is my favourite subject, I want an A in it so badly. I don't mean anything below an A1 is shít, it's just really disappointing for me.

Ah yeah, in fairness he/she got the correct answer just screwed it up in the end. I'm not even sure you'd lose a mark because you know how they always say they take the correct solution.

I doubt it'd be a slip because 4ln7 is correct, no matter what he did afterwards... Hopefully for him anyways

Full marks absolutely.

No that's correct
