My plot seems wrong so I am not sure what the problem is: (a) mistake in sol (b) mistake in coding.
A clamped, uniform string under tension \(T\) has length \(\ell\). The string is struck in the middle, giving an initial tranverse velocity distribution
\[
\dot{u}(x, 0) = \delta(x - 1/2).
\]
So the solution I obtained:
\[
u(x, t) = \frac{2}{\pi}\sum_{n=1}^{\infty}\frac{1}{n} \sin\left(\frac{n \pi}{2}\right) \sin(n\pi x)\sin(n\pi t)
\]
Is the solution correct? If so, is the plot correct?
Also, how do I find the energy of each mode?
