Q1. 2x^2 + (1/x) + C

Q2(a). Got 84/85 so got the marks.

Q2(b)(i). cos(p+q) = -13/85.

Q2(b)(ii). tan(p+q) = -85/13 = -6.46 (to 2dp).

Q3(a). Got the equation to match.

Q3(b). y = 3x - 3.

Q3©(i). C(2,3) cos it's where the perpendicular bisector of AB and the equation of CA meet.

Q3©(ii). x^2 + y^2 - 4x - 6y + 3 = 0 and i put (x-2)^2 + (y-3)^2 = 10.

Q4(a). TA = (-5, 15, 1). TB = (-40, 15, 2).

Q4(b). 50.9 degrees.

Q5. 36!!! Yeah woo that's right because I checked it on my calculator and all my friends got it as well.

Q6. y = -1.5x + 18 or 3x + 2y = 36.

Q7. 2.87 which is 2 and (13/15). Yeah woo that's right as well.

Q8. Got 1/2k.

Q9(a). Â£252Million.

Q9(b). 40 years woo what a shagger boat.

Q10. 4.5? Can anyone tell me if this vector one is right?

Q11(a). Got that x = - 1 is a solution for the cubic.

Q11(b). -1<= p >= 3. My friend got this as well and I think it is right.

I can't remember much for paper 1 except that Q9 i got sinx and cosx as 4/5 and 3/5 (can't remember which way round though) and i mucked the graph question (Q10) and for the last question(Q11(b)) I got 5 but i think it is route 5 as I forgot to unsquare it.

I finished paper 2 in about 50mins, so I had plenty of time to check it. In the past papers paper 1 was always the easier of the 2 but they must have changed it this year because I thought paper 1 was a lot harder than paper 2. To be frank, paper 2 = pish easy, paper 1 = pretty hard but manageable. Not rubbing it in btw.

4a) TA (-5, 15, 1) TB (-40, 15, 2)

b) 50.9

wasnt the angle 30 something degrees??

i got 50.9...and so did a few of my friends

I used the perp bisector from the first circle, but it seems that part c has nothing to do with b????

### #78

Somepeople I know just got 18 then stopped they will get hardly anything.

### #80

Also for the last question, I messed up a sign so ended up with p^2+2p-3, which means I got my answer reversed from the normal, anyone know how many marks I'd lose on that?
