QUESTION: Dear David

Thanks.

Using these coordinate geometry
Variation would be interesting ?.

Thanks & Regards,
Prashant s Akerkar

Answer
No I don't see why they would be interesting,if you drew a picture on a piece of paper they things plotted using this geometry would look like they would if you held it up to a mirror, or looked at it from behind, or rotating it. Not essentially different in anyway, just an arbitrary choice of which direction to call "positive."
