(Solved)
(a) A curve whose equation is in the form y = mx³ - nx where m and n are constants passes through the point (1, 2). Its gradient at the given point is 10. Find the values of m and n.
(b) Use the trapezium rule to find the area bounded by the curve y = x² + 4, the x-axis and the lines
x = 0 and x = 4. Use five ordinates.
(c) Calculate the exact area bounded by the curve, y = x² + 4, the x-axis and the lines x = 0 and x = 4. Hence find the percentage error in (b) above.
