GEOMETRY application - user's comments

[Jan 11]

I found another way to solve this problem. A test that works well for an ellipse or hyperbola is; is_concyclic.
The "is-element" test command works very well for all functions f (x) and f (x, y) and for geometric figures. A great tool. I don't know why it just doesn't work for hyperbola and ellipses (hand-drawn and according to the formula). It doesn't help to change Epsilon. This improvement can be put off as urgent for now.
