The purpose of this blog is for students to collaborate during the process of creating, recording, and writing an equation for the sound wave of a musical note. The note must come from a wind, string, or percussion instrument made by the student.

Am I going about this the right way?
Equation and Graph a=.05 2pi/ b = 1e-4 b=62831.8537 c= .0705 to the right f(x)= .05 cos ( 62831.8537x - .0705)
I think its correct, but for mine I just started the equation at the crest of a wave where it was a perfect line up with a number on the x-axis. That way there is no Horizontal Translation to worry about. I hope thats right..
I don't know what you should do about the amplitude that's inconsistent because mine seems to come out similar.
