Answer
$x=2+ \cos \theta$;$y=\sin \theta$; $0\leq \theta \leq 2 \pi$
Work Step by Step
The parametric equations are: $x=a \cos \theta; y= a\sin \theta$; $(0\leq \theta \leq 2 \pi)$
Since, $y=\sin \theta$
and $ x -2 = \cos \theta$
This can be re-written as: $x=2+ \cos \theta$
Thus, we have
$x=2+ \cos \theta$;$y=\sin \theta$; $(0\leq \theta \leq 2 \pi)$
