(a)
To Find: The period of the function.
(a)

Answer to Problem 52SR
The period of the string is
Explanation of Solution
Given:
When a guitar string is plucked, it is displaced from a fixed point in the middle of the string and vibrates back and forth, producing a musical tone. The exact tone depends on the frequency, or number of cycles per second, that the string vibrates. To produce an
Calculation:
Consider that the guitar string vibrate at 440 Hz then,
The, the period of the string is
(b)
To Find: The graph for the height of the fixed point on the string from its resting position as a function of time.
(b)

Answer to Problem 52SR
The required graph is shown in Figure 1
Explanation of Solution
Given:
Let the maximum distance above the resting position have a value of 1 unit, and let the minimum distance below this position have a value of 1 unit.
Calculation:
Consider the general equation of the vibrating string is,
Here,
The required graph is shown in Figure 1
