Calculus
« on: October 03, 2010, 08:54:04 pm »
The diagram shows part of the curve y= x3 - 6x2 + 8x + 5. The tangent to the curve at the point P(1,8) cuts the curve at the point Q.

i) Show that the x-coordinate of Q is 4.
ii) Find the area of the shaded region.

Is cubic functions even in the CIE Pure Maths Paper 1 syllabus?
Help, please :)
