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.

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]=
