+This solution is general to any formulation of the original problem,
+but gain may look different for a square or triangular wave, for
+example. It is expected that these would exhibit similar behavior
+to the sine wave because, because they would input similar amounts of
+energy on a similar time scale, but the sensitivity to waveform type
+could be investigated in the same way that this paper did, with possible
+usage of the Laplace transform to handle discontinuities, but because
+there is a general form for a sine wave and the output is proportional
+to the input, a Fourier transform could be used to either approximate
+or analytically obtain a solution for these types of waves.
