TrigFactorList

  • TrigFactorList[ expr ] factors trigonometric functions in expr, yielding a list of lists containing trigonometric monomials and exponents.
  • See notes for TrigFactor.
  • TrigFactorList tries to give results in terms of powers of Sin, Cos, Sinh and Cosh, explicitly decomposing functions like Tan.
  • See the Mathematica book: Section 3.3.7.
  • See also: FactorList, TrigToExp.

    Further Examples

    First we expand a trigonometric polynomial.

    In[1]:=

    Out[1]=

    This shows the list of the polynomial's factors paired up with their powers.

    In[2]:=

    Out[2]=

    See the Further Examples for TrigFactor, FactorList.
