Hiro is riding a carousel that is next to a wall. His horizontal distance C(t) (in m) away from the wall as a function of time t (in seconds) can be modeled
by a sinusoidal expression of the form a. cos(b. t) + d.
Att = 0, when he starts, he is closest to the wall, a distance of 2 m away. After 77 seconds he reaches his
mid-way point from the wall, which is 7 m away.
Find C(t).
t should be in radians.
C(t)
