Question

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

Answer 1

Can you draw it out?

Answer 2

i'm not sure how too

Answer 3

The period of sin is 2pi. So period of the given wave is period of sin/3 i.e. 2pi/3.

Amplitude is the max displ of the particles which is max when sin is max i.e. when sin is 1. So amplitude is 1/2
