- TrigSimplify[ <Expression> ]
- Simplifies the given trigonometric Expression.
- Examples:
TrigSimplify[1 - sin(x)^2]
gives -sin²(x)+1.TrigSimplify[sin(x)^2 - cos(x)^2 + 1]
gives 2 sin²(x).
CAS Syntax
- TrigSimplify[ <Expression> ]
- Simplifies the given trigonometric Expression.
- Examples:
TrigSimplify[1 - sin(x)^2]
gives cos²(x)TrigSimplify[sin(x)^2 - cos(x)^2 + 1]
gives 2 sin²(x).
- Note:This command works for the variable x only! (
TrigSimplify[1 - sin(y)^2]
gives -sin²(y) + 1.)
Note:
See also TrigExpand Command and TrigCombine Command.
