# P5 Edexcel 21st June - Ack!

This discussion is closed.

I've just come out of P5 and thought it was a horrible paper (compared to last year's anyway). The first six questions were fine, but I got into a real mess on the last two. How did everyone else find it?

edit: You can now find a copy of the paper on page 3!

the first 4 questions were fine, the reduction formulae was a bit of a mess, intrinsic coordinates?what are they! didnt even bother attempting that one!

number 7 was ok, i think i got the right answer and if not my method was all corect.

number 8a) was piss easy the rest was whaT?

I thought it was all fairly easy to be honest, some bits were a bit technical but nothing too hard, i think i got them all right...

I made q. 7 to be 6a and 12a^2pi/5 and for q. 8, the coordinates were (-c/t^3,-ct^3) i think.

Q 8 i attempted that part but didnt get it so i guess urs is right

on 7 I ended up with INT(root(Sin^6[x] - Sin^4[x] + Cos^6[x] - Cos^4[x]))dx

I figured I was on the right track but time wasn't looking so good I moved on to 8 because I was usually good at that kind of question. The first part of 8 was easy, then I made a stupid error on the second part and that was the mess which consumed my remaining time. Overall I think the problem with that paper wasn't so much it's difficulty (although I think it was definitely harder than the June 2003 paper) but that the questions were fairly long. Maybe an extra 30 mins and I would've finished it all ^_^

hi,I got the radian of curveture like 25/9 root 3 ,something,did anyway get that???

as long as you mean root 2 i got that (i put it as -25/9 root(2) actually, don't think it matters)

hi,I got the radian of curveture like 25/9 root 3 ,something,did anyway get that???

t= ln3

x = Cosh(t) - t

dx = Sinh(t) - 1

d2x = Cosh(t)

y = Cosh(t) + t

dy = Sinh(t) + 1

d2y = Cosh(t)

dx = 1/3

d2x = 5/3

dy = 7/3

d2y = 5/3

Radius of Curvature = (dx^2 + dy^2)^3/2 / (dx*d2y - dy*d2x)

= (1/9 + 49/9)^(3/2) / (5/9 - 35/9)

= (50/9)^(3/2) / (-30/9)

= (50^(3/2) / 27) / (-30/9)

= -(50^(3/2) / 90)

I think that's right, anyway.

cor i found that so hard its unreal. intrinsic co-ordinates?!?! help! lol. 8(a) was easy but the rest was a joke. i got 6a as well for the length but i just didnt have time to do the surface area of revolution. i filled up 18 sides of working, cant be a good sign.

yer ur rite - everything was going so well until i hit the last 3 questions and then my life got shattered lol. the woman in the exam was lookin at me very funny when after finishin the 16 page answer booklet i asked for "lots more sheets of paper please".

so annoyed wiv that paper. Anyone who says that it was easy shud be hung, drawn and quartered for lying.

So i think you are right
