Comment:
Here is my first ever Sage patch: 14532.patch. It creates an elliptic
curve from any homogeneous cubic. The cubic is transformed to Weierstrass,
and birational maps between the equations are given. The case y^2^ =
quartic is not covered.
The patch is based upon Sage 4.4.4.
The used transformations are from Section 4.4 of the course notes:
"G1CRPC: Rational Points on Curves", which I uploaded as cnotes.pdf.
Please review my patch, and provide extensive feedback.
