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.

	Result of the Trigonometric Function
a is a NULL value	NULL value
a is a special NULL value	Special NULL value
COS(a)	Cosine of number a
SIN(a)	Sine of number a
TAN(a)	Tangent of number a
COT(a)	Cotangent of number a
COSH(a)	Hyperbolic cosine of number a
SINH(a)	Hyperbolic sine of number a
TANH(a)	Hyperbolic tangent of number a
ACOS(a)	Arc cosine of number a
ASIN(a)	Arc sine of number a
ATAN(a)	Arc tangent of number a
ATAN2(a,b)	Arc tangent of the value a/b, where -p<=a<=+p and -p<=b<=+p
ASIN(a)	Arc sine of number a
RADIANS(a)	Angle in radians of the number a
DEGREES(a)	Value in degrees of the number a
