I have to admit I've never really understood the difference between a cartesian and a parametric equation.
From what I can gather, the difference is that a cartesian equation involves both the x and the y coordinates in the same equation (e.g. y = x2) while a parametric equation uses another variable as a 'go between' for the two equations (e.g. y = t2 and x = t).
Could someone please help clear this up with a simple explanation? I find it almost impossible to find the cartesian equation when asked, so I could really use some help.
Also, if anyone could offer any tips for finding the parametric equation they'd be greatly appreciated.
