Question

If we think of the
guitar string as stretched tight along the x-axis. As the string vibrates, each point on
the string moves back and forth on either side of the x-axis. Let y = f (x, t) = cos t sin x,
for 0 ≤ x ≤ π and 0 ≤ t ≤ 2π, be the displacement at time t, in milliseconds, of the
point on the string located x units from the left end.
a. Describe the cross sections of y = f (x, t) when t is fixed.
b. Describe the cross sections of y = f (x, t) when x is fixed.
c. Explain what the functions f (x, 0) and (x, 1) represent in terms of the vibrating
string.
d. Explain what the functions f (0, t) and f (1, t) represent in terms of the vibrating
string.

e. Draw the contour diagram for the displacement of the vibrating guitar string. Use
this diagram to describe the behavior of the string.
f. Find the rate of change of the displacement with respect to time at a constant
position.
g. Find the rate of change of the displacement with respect to position at a constant
time.
h. At a fixed time, what point on the string is moving the fastest?
i. At a fixed time, where is the slope of the string greatest?
