Trigonometric Function (trigonometric_function)

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

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.

Trigonometric Function (trigonometric_function)
a, b	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`, when `-pi<=a<=+pi` and `-pi<=b<=+pi`
`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`
