Dear Colleagues, I tried Bob Hanlon's TrigReduce Table changing n from "{n, 4}" to "{n, 1, 3, 0.5}": Table[{y = Sin[a]*Sin[b]^n, "=", TrigReduce[y]}, {n, 1, 3, 0.5}] // TableForm and neither the integer nor the non-integer exponent expressions evaluated whereas the original example "{n, 4}" evaluates just fine. Why? Best regards, Matthias Bode Sal. Oppenheim jr. & Cie.
