Question #3 (Medium): Tracing the Direction of the Parametric Curve
Given the parametric value within the interval, starting from the lower bound for going all the way up
to the upper bound of the interval for , the direction of the curve follows how and combination
moves as the values moves along the interval.
1) Eliminate the parameter to find the Cartesian equation of the curve.
2) Sketch the curve and show in an arrow the direction the curve is traced as the parameter
