• r = 3 cos(theta) where 0 <= theta <= Pi/2 (Quicktime format)
  Example 3 in class
• r = 3 cos(theta) where 0 <= theta <= Pi (Quicktime format)
  Example 3 in class again
• r = 3 cos(theta) where 0 <= theta <= 2 Pi (Quicktime format)
  Example 3 in class yet again
• r = cos(2 theta) where 0 <= theta <= Pi/2 (Quicktime format)
  Example 4 in class
• r = cos(2 theta) where 0 <= theta <= 2Pi (Quicktime format)
  Example 4 in class again
• r = 1+ 2 cos(theta) where 0 <= theta <= 2Pi (Quicktime format)
  Example 5 in class
