The displacement of a standing wave on a string is given by D=3.6sin(.54x)cos(37t), where x and D are in centimeters and t is in seconds.

What is the distance in cm between the nodes in centimeters?

Give the amplitude of each of the component waves, meaning that there two, in cm.

Give the frequency of each of the component waves in Hz.

Give the speed of each of the component waves in cm/s.

Find the speed of a particle of the string at x=3.60cm when t=2.8s
