Question 604168
a sound wave has a period of 0.06 seconds and an amplitude of 4 units. sketch a graph of the sound wave.
---
y = a*sin(bx+c)
---
period = (2pi)/b = 0.06 
b = (2pi/0.06)
---
a = 4
---
y = 4*sin[(2pi/0.06)x]
----
{{{graph(400,400,-0.12,0.12,-10,10,4*sin((2/0.06)pi*x))}}}
---
Note: The graph covers the interval -0.12<= x <=0.12, which
is four periods of the curve.
