Diagram shows part of the curve y= -8x ³ - 1
The curve intersects the x-axis at S and the y-axis at T. Line SU is a tangent to the curve at point S
(a) Find the coordinates of points S, T and U.
(b) Hence, calculate the area of the shaded region
c) the volume generated, in terms of π , when the area bounded by the curve, x-axis and y-axis is rotated through 360° about the x-axis.
