SOLUTION: Please help me sketch a graph of the polar equation: {{{ r= 4/2+cos(theta) }}} Also, express the equation in rectangular coordinates. So far, I have the graph done. It's more

Question 861467: Please help me sketch a graph of the polar equation:
Also, express the equation in rectangular coordinates.
So far, I have the graph done. It's more of an oval shape compared to a circle. the x,y axis coordinates are: (1,0) (2,0) (-4,0) (0,-2)
As for the Equation part, so far I have:
r(2+cos(theta)=4
