Answer:
-15+9=-6 --------> -6-12=-18
15 represents where he started, then he rises upward 9 and then gets to 6. Afterwards he goes down 12 and ends up at 18 which is 3 feet lower then where he originally started.

Step-by-step explanation:
If f(θ) = a cos(bθ), then from the first condition we find
f(0) = 3 ⇒ a cos(0) = 3 ⇒ a = 3
Together with the other conditions, it's evident that f(θ) has a period of π, so
2π/b = π ⇒ b = 2
so that
f(θ) = 3 cos(2θ)
