- 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).
Note: See also TrigExpand Command and TrigSimplify Command.
