Question 631103: Musical notes can be represented by the trigonometric function y=sin(2pi qx) where q is the frequency of the note and x is the time in seconds that the note is played. the equation y=1.5sin(524pi t), where t represents a sound wave produced by the note middle C. What is the value of q, the musical frequency of middle C?
(1)1.5
(2)262
(3)262 pi
(4)524 pi

--------------
It's 524pi/2pi = 262 Hz
That's middle C based on the international A-440 Hz scale.
-----------------
Not sure about --- y=sin(2pi qx) where q is the frequency of the note and x is the time in seconds that the note is played.
x = time in seconds the note is played??
