Convert R=(12)/4+8sin the theta to rectangular form

kompoz [17]

$r=\dfrac{12}{4+8\sin\theta}=\dfrac3{1+2\sin\theta}$

Let $y=2\sin\theta$ , and recall that in polar coordinates, $r=\sqrt{x^2+y^2}$ . This means you have

$\sqrt{x^2+y^2}=\dfrac3{1+y}$

You can stop there, or try to find something that looks somewhat nicer.

$x^2+y^2=\dfrac9{(1+y)^2}$
