 * I am not sure what this above is supposed to mean. Perhaps your looking for a proof in this specific case?  If this is so both sides are easily calculated and equal, You could try using Octave to do the calculation for you if you just want a quick verification.  Thenub314 (talk) 11:09, 8 June 2010 (UTC)
