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

Replace the polar equation by an equivalent Cartesian (rectangular) equation. Then identify or describe the graph.

****Let's just make x = theta because I can't find a theta symbol*****

r = 2cos(x) + 2sin(x)

2. Relevant equations

none?

3. The attempt at a solution

x = rcos(x) = (2cos(x) + 2sin(x)) * cos(x)

y = rsin(x) = (2cos(x) + 2sin(x)) *sin(x)

No idea what do to from here.

Thanks in advance
