Sketching a Curve by Eliminating the Parameter A pair

of parametric equations is given. (a) Sketch the curve represented

by the parametric equations. Use arrows to indicate the direction of

the curve as t increases. (b) Find a rectangular-coordinate equation

for the curve by eliminating the parameter.
