Sep 1	comment	Canonical to Parametric, Ellipse Equation I'm doing this for myself, I'm revising some geometry and linear algebra to better understand some concepts in Computer Graphics. But I had pretty rigorous math teachers on my first semesters, so I got this "fear" of doing wrong things. Thank you for you enlightening explanations.
Sep 1	comment	Canonical to Parametric, Ellipse Equation I was thinking in make some supositions to hold my equatios, I think that it's clear now, I can accept this fact now ^^. Thank you very much.

Sep 1	comment	Canonical to Parametric, Ellipse Equation @Thijs Laarhoven, surely. It's easy to show that with a counter example.
Sep 1	comment	Canonical to Parametric, Ellipse Equation @Hennig Makholm. What's the correct way to do this, I mean, without dodgy steps, because I was only able to dos this. And what do you mean "by inspection"? And finnaly, an arbitrary solution would be a (x,y) point? Thank you, you are really helping me.
