Since you do not need an example for each case I will provide just one: In[11]:= Expand[Sin[2x]] Out[11]= Sin[2*x] In[12]:= Expand[Sin[2x],Trig->True] Out[12]= 2*Cos[x]*Sin[x] Andrzej Kozlowski Toyama International University JAPAN http://platon.c.u-tokyo.ac.jp/andrzej/ On Wednesday, July 3, 2002, at 06:14 PM, Ersek, Ted R wrote: > 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.
