- 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).
