Trigonometric Function (trigonometric_function)

A trigonometric function (trigonometric_function) is a function that supplies a numeric value as a result.

Syntax

<trigonometric_function> ::=
  COS     ( <expression> )
| SIN     ( <expression> )
| TAN     ( <expression> )
| COT     ( <expression> )
| COSH    ( <expression> )
| SINH    ( <expression> )
| TANH    ( <expression> )
| ACOS    ( <expression> )
| ASIN    ( <expression> )
| ATAN    ( <expression> )
| ATAN2   ( <expression>, <expression> )
| RADIANS ( <expression> )
| DEGREES ( <expression> )

Explanation

All expressions (expression) in every trigonometric function identify an angle in radians and are denoted with a and b below. The only exception to this is the RADIANS function.
