Polar Graphing

  1. Apr 3, 2008 #1
    1. The problem statement, all variables and given/known data
    Find the Maximum and Minimum of the following equation.

    3. The attempt at a solution
    Max- 2-2 cos (0[tex]\pi[/tex])=0

    Min 2-2cos([tex]\pi[/tex])=4

    Do i just have these backwards?

    0<4, so yes, you have them backwards. 4 is the max, 0 is the min.

    I'm wondering how you determined that
    And, by the way, an equation does not have a max or min- a function does. An equation does not even have a "value" to be max or min.
