Days left till C2: 1

Hi guys, so I decided to open a thread for the C2 Edexcel exam which is on 22 may. This is the last RESIT for this spec. You can post any of your doubts or helpful resources here for others. I think by looking at the exam, we will have high grade boundaries as it'll be for retakes only but we have lots of resources too I guess.

Good luck Everyone!

-----------------------------------------------------------------------
Ok that paper was hard compared to the previous years, I hope grade boundaries are low, Im thinking maybe 65 - A, 60-B?

Y=-3
???

Q6 integration
288

Q7 can't remember it
4 values for θ:
-69.1
-20.9
15
75

logx600=3, x=8.43
You should have got X^5 = 2781, part ii)
Then X^5 = 3x3^6
Therefore X=3^7/5

0.283
0.709
B) perimeter 7.2
C) area, 1/2 r^2 (θ-sinθ)

10)
part a) proof of area/perimeter
7.16

Centre of circle (3/2, -3) ?
Line of tangent to point (5,-3) - 12y=7x+71 or something

Yeah, doing all the core modules. Got a b last time, only needed 3 marks for an A. But I figure I might as well try for the *

Area under the curve was like 96, then it was a matter of fact of taking away 1 triangle from another and that 96

Guys what did you get for the Center of the circle? (2/3,-3) if so what was the equation for the line. Because point P was (5,-3) and from the gradient forumula y1-y2 you would get 0?? Please help lol

The circle equation was x^2+3x+Y^2+6y=1? So by completeinf the square you shave have (y+3)^2 which gives Y co-ordinate -3?
