Problem $11\mathrm{.}091-$ Analyze the motion of a particle given $x$ and $y$ as functions of $t$

The motion of a particle is defined by the equations $x=\frac{4cost-2}{2-cost}$ and $y=\frac{3sint}{2-cost},$ where $x$ and $y$ are expressed in feet and $t$ in seconds.

Problem $11\mathrm{.}091.$c $-$ Analyze the motion of a particle given $x$ and $y$ as functions of $t-$find velocity

Determine the velocity when $t=1s.($Round the final answer to three decimal places. Include a minus sign if necessary.$)$ The velocity is $f\frac{t}{s}$uarr.
