In the figure triangles ACB and APO are equilateral.
(i) Explain why /_BAO = /_PAC
B)
(i) The diagram shows part of the graphs of both y=sec x and y= (4Sqr2 /Pi)x
Show that (Pi/4 , Sqr 2) satisfies both of these equations.
(ii) The area bounded by the curve y=secx, y= (4Sqr2 /Pi)x and the y-axis is rotated about the x-axis. Find the volume of the solid of revolution.
