An ambulance with a rotating beam of light is parked 12 feet from a building. the function d=12tan2πt describes the distance, d, in feet, of the rotating beam of light from point c after t seconds.
a. graph the function on the interval [0,2].
b. for what values of t in [0,2] is the function undefined? what does this mean in terms of the rotating beam of light in the figure shown?
