My question:

Find the polar equation of the "Folium of Descartes" -> 
x^3 + y^3 = 3axy with x+y+a=0 as an asymptote.

I think I need to do something with x=rcost, and y = rsint.
 
Thanks for any help,
Scott

To find the polar equation of x^3 + y^3 = 3axy with x+y+a=0 as an 
asymptote, you need to substitute x = r*Cos[t], y = r*Sin[t] into the 
Cartesian equation, and simplify.  Why do you do this?
