Question:
Sinus cosinus functions
A merry-go-round takes 15 seconds to complete one revolution/spin. Within that time, each horse moves up and down five times. The vertical motion of the horse spans a range of 50 cm, and the horse is 1 m high at its vertically centre position. (Hint: Sine Wave/Function)
a. Sketch a graph of the height of the horse over time for one complete revolution/spin of the ride, starting with the horse at its lowest position, where h is the height of the horse in centimetres and t is the time elapsed in seconds.
b. State the equation of the SINE function that relates the height of the horse, h, as a function of time, t.
