This mathematics document discusses converting between parametric and Cartesian forms of curves. It contains exercises from a textbook that ask students to describe curves using parameters and to convert parametric equations into Cartesian coordinate equations. The objectives are to use parameters to describe curves and change parametric equations into standard Cartesian x-y coordinate form.

1. Starter Differentiate: a) b) c)

2. Objectives: to describe a curve using a parameter to convert the parametric form to the Cartesian form
