An alternate derivation is provided for a recent refinement of the Cauchy-Schwarz inequality which shows that the refinement is not optimal. The optimal result is then derived and shown to be valid under very general conditions. Matthew Marmorino, Indiana University South Bend 8 September 2014 Please follow this link.
