i have this equation: [tex]r=\sqrt{1+sin2\theta}[/tex](adsbygoogle = window.adsbygoogle || []).push({});

and am to convert to cartesian equation and from the equation see that it consists of two circles and directly note the radii of the cirlcles from the equation.

so far i have manipulated it and gotten:

[tex]x^6 + 3x^4 y^2 + 3 x^2 y^4 + y^6 - x^4 -6x^2 y^2 - 4x^3 y -y^4 - 4y^3 x=0[/tex]

any suggestions on how to get it into the required form?

thanks
