    A Couple Homework Problems

    (1) Find the area of the region bounded by the given curves.
    y = cos(x) y = cos^3(x) x = 0 x = pi/2

    (2) Find the area of the region bounded by the hyperbola 9x^2 - 4y^2 = 36 and the line x = 3.

    (3) Find the volume obtained by rotating the region bounded by the given curves about x-axis.
    y = cos(x) x = 0 x = (pi/2) y = 0
