Hope everyone gets the grades they deserve, and I wish everyone the best of luck for the rest of your exams

paper 2:
Q3, did anyone get zero for the limit?
Q5, k=5 n= 0.5?

These are exactly what I put for both questions. Looks like k was wrong but n is right

oh, thank Christ, that's ten marks definitely in the bag

thank you Wolfram Alpha and your usefulness

Question 16 in the multiple choice, was the answer a? And is it 70 percent for a A?

I'm with you there. I know now that I've failed this. I can't even cry, I just feel like ****. Need to snap out of this before German!! **** my life. I hate maths, I hate it!

So what was the correct answer for the Integration Area question?

[wboyd]

A got zero as the limit which was quite off putting, but yes

paper 2:

Zero was the limit as there was no b. And no I got 2^5 which is 32, I can work the question through for people if they wanna see it.

Changes every year but it's usually around 75%

God no it didn't!

I agree, easy paper 1.
But paper 2 wtf!?

10 mark Integration
Followed quickly by a 7 mark trigonometric integration.
Followed by a 9 mark Problem Solving!?

Give me an extra half hour in that exam, I would have had that problem solving sorted. had gotten so far when my time ran out. Had established both radiuses, both centres, the distance between both centres, and that p had to be less than --108 for my radius expression to hold true.
But I did the integration, and did the 7 marker, did every other question in the paper.

****ing 2010, first English and now Maths! Why're we getting the harder papers!?

Did you see the last 2 questions of 2010's paper 2?!?!

I'm sure you'll've done better than you thought (it happends to practically everyone..) All the best.

Same!!! How many marks do you think you'll get for that question?

3 or 4 maybe? idk

there was a question where the graph cuts the x-axis and y-axis
f(x)= (x-2)(x2+1)

For x-axis i got 2 and +-1
For Y-axis I got -2

It's 2 and sqrt(-1) which has no solutions, therefore the only answer is 2.

My friends and i got 21.something units squared.

(Original post by Joshp)
K=32 and n=1/2
For the wave function, Root34sin(x + 5.25)?

Wait how did you get 5.25?

Haha me too! but after you think about it, it's quite obvious that it is going to converge on 0 if you keep halving the numbers.

Ahh okay thanks, I figured my answer was a little far out :L 48 or something.. should pick up the majority of the marks for my working though

You have to change the answer into radians

[rajveers]

what did everyone get for 23 - non calc?

(Original post by chr1stopher11)

The answer didn't lie in quadrant 1, it was in the 3rd (I think), so whatever you got you had to take away from 6.28 (2pi).
