The provided statement makes sense.

Work Step by Step

Curves that are not graphs of the functions are not easy to describe. Parametric equations make the interpretation of such curves easier. For example: Let us consider the equation of a circle. Parametric equations of a circle are provided by $\begin{align} & x=a\sin t \\ & y=a\cos t \\ \end{align}$ Where “a” is the radius of the circle. Parametric equations make this interpretation easier. Thus, the provided statement makes sense.
