Trig option

The usage message for the built-in symbol Trig is shown below.

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.

Simplify and FullSimplify have the default setting (Trig→True) and all

other functions above have the default setting (Trig→False). I

searched through all available documentation and couldn't find a single

example to demonstrate this option. The examples using the Trig option below

were provided by Allan Hayes and Andrzej Kozlowski. In each case the

original expression would be returned if it were not for the use of (Trig

→True).
