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)
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
