Suppose that a quadcopter drone is approaching you at a speed of 10 m/s (which is faster than you can run away, unless you are an olympic sprinter) and at a constant altitude of 5 meters. Further suppose that you are frozen with fear and just stay where you are. 

a) Write parametric formulas for the distance between you and the drone as a function of time. 

b) Make a reasonable graph of the results. 

c) Write a single parametric formula for the angle between you and the drone. That is, if you were tracking the drone with a camera as it came straight toward you, how would the angle change with time? I would set angle=0 as purely vertical, angle=-90 degrees as horizontal one way, and angle=+90 degrees as h
