- TrigSimplify[ <Expression> ]
- Simplifies the given trigonometric Expression.
- Example:
TrigSimplify[1 - sin(x)^2]
gives cos²(x).
- Note:See also TrigExpand Command and TrigCombine Command.

- TrigSimplify[ <Expression> ]
- Simplifies the given trigonometric Expression.
- Example:
TrigSimplify[sen(x)^2 - cos(x)^2 + 1 ]
gives 2 sen(x)².
- Note:
- This command works for the variable x only! (
TrigSimplify[1 - sin(y)^2]
gives -sin²(y) + 1.) - See also TrigExpand Command and TrigCombine Command.
- This command works for the variable x only! (
