Missing 1/2[edit]
I don't have time to correct it, but in the derivation of the eigenvalues for the discrete case there is a ½ missing in the argument of the sine. This is due to a mistake in the final application of the trig identity. The factor ½ appears correctly in the formula above. — Preceding unsigned comment added by 62.141.177.119 (talk • contribs)
