# Math trigonometric VCL features

Trigonometric functions.

## Functions

• math.acos() — Computes the principal value of the arc cosine of its argument x.
• math.acosh() — Computes the inverse hyperbolic cosine of its argument x.
• math.asin() — Computes the principal value of the arc sine of the argument x.
• math.asinh() — Computes the inverse hyperbolic sine of its argument x.
• math.atan() — Computes the principal value of the arc tangent of its argument x.
• math.atan2() — Computes the principal value of the arc tangent of y/x, using the signs of both arguments to determine the quadrant of the Return Value.
• math.atanh() — Computes the inverse hyperbolic tangent of its argument x.
• math.cos() — Computes the cosine of its argument x, measured in radians.
• math.cosh() — Computes the hyperbolic cosine of its argument x.
• math.sin() — Computes the sine of its argument x, measured in radians.
• math.sinh() — Computes the hyperbolic sine of its argument x.
• math.sqrt() — Computes the square root of its argument x.
• math.tan() — Computes the tangent of its argument x, measured in radians.
• math.tanh() — Computes the hyperbolic tangent of its argument x.
