equations. 
Introduction
of parametric equations. Note the context of the
problem to determine if angles are in degrees or radians! Explain
JR: Why are these equations called parametric? What makes them that way? 
1.
Write parametric equations for the scenario:The world's latest golfing sensation, Cheetah Forest, selects his sand wedge (56° loft) and will strike the ball at 88 feet per second. Determine how far the ball will travel horizontally and vertically.2. An object moves along the path defined by y = x^{3} + 3. The xcoordinate satisfies the equation x(t) = t + 1. a) In what direction is the object moving? b) What is the corresponding y(t)?
