Precal S2 Day 36 ­ Plane Curves & Parametric Models.notebook 2 March 01, 2018 Parametric Functions & Plane Curves Last time, we defined parametric equations as a pair of functions for x and y given in terms of the parameter t . To change an equation from parametric form to rectangular form: Solve the simpler equation for t (if you can't tell which is simpler, just use the x equation) Substitute the result for the t in the other equation Simplify (and isolate y if possible) There are usually multiple ways to write a pair of parametric equations for a given rectangular equation. The simplest way to write a pair of parametric equations for a function of y in terms of x is to make one equation x = t , and then substitute t for x
