TrigFactor

  • TrigFactor[ expr ] factors trigonometric functions in expr.
  • TrigFactor operates on both circular and hyperbolic functions.
  • TrigFactor splits up sums and integer multiples that appear in arguments of trigonometric functions, and then factors resulting polynomials in trigonometric functions, using trigonometric identities when possible.
  • See the Mathematica book: Section 1.4.5Section 3.3.7.
  • See also: TrigExpand, TrigReduce, TrigToExp, Factor, Simplify, FullSimplify.

    Further Examples

    Here is a trigonometric polynomial.

    In[1]:=

    Out[1]=

    TrigFactor and TrigReduce are approximately opposite. TrigFactor writes the polynomial as a product.

    In[2]:=

    Out[2]=

    TrigReduce writes the polynomial as a sum involving no explicit products or powers.

    In[3]:=

    Out[3]=

    In[4]:=

    Here are similar examples for a hyperbolic polynomial.

    In[5]:=

    Out[5]=

    In[6]:=

    Out[6]=

    In[7]:=
