Far simpler: as , we have ; hence what we were asked to solve is from which . Obviously , and give values of in the desired range!
even better, nice :P

What's yr firm? Are you majoring in math in future?
My firm is Warwick and my insurance is Nottingham and yeah I'm 'majoring' in maths, how about you?

I've got to be honest, I think I could have done much better in this exam, I guess nerves got to me .

I am not going into math. I've an offer to study engineering at Imperial. Though they didn't make AEA a requirement, the admission person encourages me to take that.

I understand that sometimes under exam conditions, you can't seem to perform to yr max. It happens to me during all my school internal exams, and in fact for my A levels too, when I am worrying how much marks I lost due to my negligence.

This is how I did question 1:

$let \ \theta +35^{\circ} = A \\ and \ let \ \theta -53^{\circ} = B \\tanA=CotB \\ \frac{SinA}{CosA}=\frac{CosB}{SinB} \\ SinASinB=CosACosB \\ CosACosB-SinASinB=0 \\ Cos(A+B)=0 \\ Cos(2\theta -18^{\circ})=0 \\ 2\theta -18^{\circ}= 90^{\circ}, 270^{\circ} \\ \theta = 54^{\circ},144^{\circ}$
You are a genius my friend

I didn't think of that at all Realised I could've done tan x = cot (90 - x) today

But that's not true that opposite angles in a kite add up to 180 deg; it's coincidental that both opposite angles add up to 180 deg, as one of the angle is 90 deg.

Assume there are 2 similar angles of 100 deg in a kite. Do the remaining opposite angles add up to 180 deg?

Anw, do u require AEA for yr offer?
I thought it was true for 4 sided shapes.
Oh well!

Yeah I require it for my insurance.

How'd you find it, man?

Absolutely crap.

I too thought Q1 was just a typo.

I found the vectors question especially difficult too.

I thought it was a very difficult paper - don't remember any of the others being as difficult at all.

Same.

I really would have liked a Merit here. ffs why was this one of the hardest years.

It was like the worst year ever for the AEA and STEP II. Just *******s really.

Yep. I was expecting a 2 for STEP I but I just froze in the exam. When I tried it again a day later I got quite a lot of the Qs. I hate that.
11. What do you guys reckon the grade boundaries will be for a distinction? I'm seriously hoping for sub-70.

Hoping for something like that aswell but DFranklin reckons there'll be normal boundaries
13. On that last question, how the hell were you meant to find p and q?

Well, the vertical asymptote had been shifted to the y-axis, i.e. 3 to the left. So p = 3.

If you look at the original graph, the y-values of the stationary points were -2 and -10 if I remember correctly. They're symmetrical about the line y=-6. If you look to the translated graph, they both lie the same distance above the x-axis, so the line of symettry y=-6 has been shifted up 6 to the x-axis. Hence q = 6.

Ugh. ****ing exams

I got p=3, q=6 ?
17. So is anyone doing the solutions?

Did you send the paper to Mr. M and ask him?
19. (Original post by ElMoro)

p is the translation to the left hence 3 as the asymptote move by 3 to the left. q is the shift up, but as the curve,after taking the modulus, is symmetrical in y it means C and D have the same y-coordinate, therefore, before taking the modulus the y coordinate of C is negative that of D, a value of 6 does that.
For me I thought the paper was hard, and the grade boundaries would probably be around 70 as usualll.. I totally messed up on question 5 on the last bit, cus I thought that freaking thing we had to show was an identity, I feel so stupid nowww for not just subbing an a value innn.. I als messed up my calculations a bit in the vectors question in part d). Otherwise I think i did okay, good thing is i don't need it for an offer or anything haha..
20. Sorry just realised someone made the same point about p and q earlier.
