This section describes functions that have not yet been classifed. These will be moved to independent sections in a future.
With loading the file todo_parametrize/todo_parametrize.rr
the function paramerize is installed.
The function finds a parametric expression of a given rational curve.
As to details, see
See section `' in A package for algebraic curves (in Japanese).
