I was looking at the Edexcel P3, it doesn't seem that bad. I done CCEA, can anyone work out the correct answer to this question
Find the coordinates of any turning points on the curve y=3x^2/e^x (7 marks) (ii) determine the nature of these turning points (3)
i think that was the only real hard question on our P3, and this one too
prove the identity
sin2acos2a /cosA -sinAsin2a =tan2a
(7 marks)
