Cylindrical Coordinates

  1. Sep 20, 2006 #1
    I'm having some trouble understanding exactly how to graph this problem using cylindrical coordinates. The coordinates they give me is r=2cos(theta)

    How do I go about beginning to determine how to graph this with only the radius?

    Anywhere the angle is pi/3, r = 1, no matter what z is--the horizontal cross section is the same as you move up or down. The set of points satisfying that equation is therefore a set of vertical lines. To find the cross section (in a form that you can recognize) you could start by converting the equation to rectangular coordinates.
