So I'll write that. It's largely a case of spotting something nice (grace_'s idea sounds good to me, but I'm not sure it's completely right), but if you really wanted to you could put x=t, plug it into that cartesian equation and solve the quartic equation for y in terms of t; it'd be bloody nasty, but it'd be an acceptable parametrisation. Differential Equations. into a polar equation and calculate r. Enter the real and imaginary parts a and b and the number of decimals desired and press "Convert to Polar and Exponential".
