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.)
