## Homework Statement

r=(1/(2+cos(θ))

## Homework Equations

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

rcosθ=x

rsinθ=y

## 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.
