##### If a violin string is plucked (pulled aside and let go), it is possible to find a formula \$f(x, t)\$ for the displacement at time \$t\$ of any point \$x\$ of the vibrating string from its equilibrium position. It turns out that in solving this problem we need to expand the function \$f(x, 0),\$ whose graph is the initial shape of the string, in a Fourier sine series. Find this series if a string of length \$l\$ is pulled aside a small distance \$h\$ at its center, as shown.
