(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

r=(1/(2+cos(θ))

2. Relevant equations

r=sqrt(x^2+y^2)

rcosθ=x

rsinθ=y

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.
