Part (a): 26. Use the best method available to find the volume of the region bounded by sin y x and 2 y x revolved about (a) y = 1, (b) x = 1, (c) the y -axis, and (d) the x -axis. Section 5.4 4. Approximate the length of the curve using n secant lines for n = 2; n = 4. ln ,1 3 y x x
14. Compute the arc length exactly.
