A circle has its center located at the point $(5,-3)$ and its radius is $8$. What are the parametric equations that describe this circle?

An ellipse has its center at $(-3,5),$ with vertices $6$ units above and below the center, and endpoints of its minor axis $3$ units to the left and right of the center. Find the parametric equations for this ellipse.

Determine the parametric equations for the line segment connecting the points (-3, 5) and (4, -2).
