Repeat Exercise 18 for the case where the displaced profile of the string is as shown in Figure 7.22.
Repeat Exercise 18
A tightly stretched flexible uniform string has its ends fixed at the points x = 0 and x = l. The midpoint of the string is displaced a distance a, as shown in Figure 7.21. If f(x) denotes the displaced profile of the string, express f(x) as a Fourier series expansion consisting only of sine terms
