A wave is modeled with the function y = 1/2 sin 3Θ, where Θ is in radius. Describe the graph of this function, including its period, amplitude, and points of intersection with the x-axis.

My answers are

Amplitude = 1/2

Period = 2pi/3

Intersection= (0,0), (π/3,0) and (2π/3,0)

  1. correct
    if your domain for the intersection is 0≤ Ø ≤ 2π
    you should also include π, 4π/3, 5π/3, and 2π
