Hello mathgroup, The usage message for Trig says: Trig is an option for algebraic manipulation functions which specifies whether trigonometric functions should be treated as rational functions of exponentials. --------- The built-in functions that have the Trig option are: Apart, ApartSquareFree, Cancel, Coefficient, CoefficientList, Collect, Denominator, Expand, ExpandAll, ExpandDenominator, ExpandNumerator, Exponent, Factor, FactorList, FactorSquareFree, FactorSquareFreeList, FactorTerms, FactorTermsList, FullSimplify, Numerator, PolynomialGCD, PolynomialLCM, PolynomialMod, Resultant, Simplify, Together. After searching all available documentation I can't find a single example of where f[expr, Trig->True] would give a different result than f[expr, Trig->False], and I can't come up with one on my own. Can you give some examples. An example for each function above is not necessary. --------- Thanks, Ted Ersek Get Mathematica tips, tricks from http://www.verbeia.com/mathematica/tips/Tricks.html
