- 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)*.

## 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 all variables in the CAS View, but only for variables "x", "y" and "z" in the Algebra View!
