Inquiry into the origin of parametric equations.

[captpetorius]

I'm trying to find information on the origin of parametric equations. Such as who developed them, and around what time. Unfortunately I can't seem to find any information, beyond the basics of what parametric equations are. I was hoping someone here might be able to point me in the right direction.
Thanks!

I don't think you are going to be able to find such information. It goes too far back and people were using "parametric" equations long before that name was used. As soon as people started using separate equations for the different coordinates of a moving object they were using "parametric equations".
