TrigCombine[ <Expression> ]
Transformes a trigonometric expression including products of trigonometric functions into an expression without products involving sums of variables.
Example: TrigCombine[sin(x)cos(3x)] gives \frac{sin(4x)-sin(2x)}{2}.
TrigCombine[ <Expression>, <Target Function> ]
Transformes a trigonometric expression including products of trigonometric functions into an expression without products involving sums of variables, preferring the given target function.
Example: TrigCombine[(tan(p)+tan(q))/(1-tan(p) tan(q)),tan(x)] gives tan(p+q).
