Trigonometric Function (trigonometric_function)
A trigonometric function ( trigonometric_function) is a function that produces a numerical value.
<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.
