A curve is described in polar coordinates . Find parametric equations for $x$ and $y$ and plot the curve. A curve is described in polar coordinates by the equations
$$ r = t; \theta  = 3 \cos t; 0 ≤ t ≤ 10  $$
Find parametric equations for $x$ and $y.$
I cannot convert it into parametric form

the transformation between cartesian $(x, y)$ and the polar $[r, \theta]$ are given by $$x = r \cos \theta, y = \sin \theta $$ so the parametric equation in cartesian is $$x = t \cos (3 \cos t), y = t \sin (3 \cos t),0 \le t \le 10. $$
the curve follows a spiral bouncing  back and forth between the rays $\theta = -3$ and $\theta = 3$ while getting farther and farther.
