What a disaster.

cormac17

it wasnt 2 bad!!!! not as bad as paper 1 neway!!!!

the further cal was though:(:(
trig was hard neuf 2,,,didnt get 5 (b) at all:(,,but Q 2,4,6 were my life savers:D,,i defo passed neway:D thats all i was worryin bout,,failin!!

What a bitch of a paper...DidQ1,2,3,4,5,8....

carlowboy

I did all of 1-8 but I would think 1-5 and 8 were my 6 best.

Thank god someone else thinks so too! Couldn't get Q1 (a).. I hadn't looked over them Just couldn't remember. Coudn't get the Trig C parts... so close.. forgot to go back to the last question on the line (iii)

______

i done 1, 2, 3, 4, 5 and 8.

i thought it went brilliant, gonna refuse to dissect the paper becuase right now i feel i've passed on it alone.

and why would i want to lose that feeling

david

Got it all! Q2,4,5,6,7,8

euwwy deuwwy

That paper really annoyed me!!!!!!!! I made so many stupid mistakes!! What was the story with the (t) scaler in the part C vectors question? Nd what did people get for Q6c iii.Its the one where you have to work out extra values for w and r or something. I didnt get it finished nyway.

Horrible..:(

to prove sin(A+B)

It said derive so you could just stick in -B...... right?

I was going brilliantly, like I found the paper, dare I say it, 'easy' until the option section that is. I lost the blue maths book that covers the option section so couldn't revise until this morning when I borrowed it off someone. I'll be hoping for attempt marks in that section. I decided to do the probability option as well since it didn't look too bad but couldnt get part c)
Ah well, I don't need to count maths anyway unless I was to get sick and miss another exam

well.. crap. I didn't see the prove sin(a+b) and only derived from cos(a+b). 20 marks lost?

What was with that "t" in the vectors question??? What did you do with it. I'd say i got about 60% on the paper, Q8 i could only do part (a) and the maclaurn series in part (b). So hopefully that will get me 20 marks in that question. pert (c) i did by integration (not by parts), but looked at a formual to do with tan^-1 in the tables. Im sure its wrong though, because it said it needed x/a but there was only x......

Nehpets

x is x/1 so a is one. But that forumla isn't for integration (I think)

I left the t in the vectors question but I also left in the i's and j's after I multplied them

Circle not too bad but I don't think i got out C fully. Vectors much of the same as with the line. I think I may have got all of 4 and certainly 5. Option was a total nightmare, couldn't do a or b ii.

carlowboy

The way I see it is that if you knew your proofs, the SEC seems to want to give everyone a B from the (a) and (b) parts from both papers. They're not so nice with the As though as the (c) parts in some questions were quite tricky. If you want a B, it was a lovely paper IMO.

genericgoon

Not too bad couldnt get the C part of teh first trig question or the c part of the option and one part of the first probability/combination c part. Id say i passed and hopefully a B altogether with both papers.

whatshername!!

I hated question 8. did anyone use integration by parts aload of people i was talking to didnt but i did i think i got it wrong though coz i got 0

Nehpets

For part c integration by parts was needed. the answer is on the other thread

Why wouldn't you use integration by parts? It's question 8. Normal integration isn't on paper 2....

Nehpets

lol, that's true. When I looked at it nightmares of evaluating pi came to mind but then I realised what it was. Part a was harder

Thats what i thought too but a load of people said it today after the exam and i was just wondering

Part (a) was a very basic and easy question, but it required you to actually understand calculus propery and be able to link it with algebra.

carlowboy

I would say extremely basic was part a. Do they do that in ordinary?

eily

im actually not going to college. damn my pride!
