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)
53/125 is the simplest form for this question.

400 * 2% = 8
A: 8 * 6 = $48
B: 400 + 48 = $448
