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 only for variables "x", "y" and "z" in the Menu view algebra.svg Algebra View

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).
