1 answer:
You have a sinusoid function given in the form:
y = A cos (ωθ)
Indeed, you have:
<span>y = 1/4 cos (2π/3 θ)
with A = 1/4 and ω = 2π/3
In order to find the period, you need to remember that:
T = 2π / ω = 2π / 2π/3 = 2<span>π × 3 / </span>2<span>π = 3</span>
The Amplitude will simpy be A = 1/4
