Did Edexcel employ Satan to write this paper? That last question was worth at least 13 marks and was full of long bull**** text.
Frigging UCAS and A Levels. Every year they want higher grades for Uni, from AAA to A*A*A and then they put the exams harder! Da hell? I hope I did my a level in 2009. Woul have been a breeze in maths.
For the trig question, I wrote tan as sin/cos and then took sin out as a common factor and equated it to zero.
Anyone else did in this way?
For the area I got 38.9
For k I got 5 root 3
Overall pretty satisfied with myself.
K wasn't 5root3. If you got that, it's because when you squared 6root5, you did
6 x (root5)^2 = 6 x 5 =30
6 x 6 x root5 x root5 = 6 x 6 x 5 = 180
I thought the paper was fairly generous. My one concern, is that when finding the second derivative in part d of the last question, I acciedently wrote dy^2/dx^2. When it's actually d^2y/dx^2... Will I have lost an accuracy mark, as technically the notation of my second derivative was incorrect?
