Homework Help: Converting a polar equation to an x,y equation

  1. Mar 27, 2012 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Not sure what first step to take. This problem looks so simple, but I can't seem to get far on paper. Not sure if I should multiply both sides by 2+cos and then multiply both sides by r, or if I should change the fraction as (2+cos)^-1.
