Trigonometric Functions

Applies to: ✅ Data 360 SQL ✅ Tableau Hyper API

Functions for computing trigonometric values. All arguments are in radians.

Function (radians)	Description
`acos(x)`	inverse cosine
`asin(x)`	inverse sine
`atan(x)`	inverse tangent
`atan2(y, x)`	inverse tangent of `y/x`
`cos(x)`	cosine
`cot(x)`	cotangent
`sin(x)`	sine
`tan(x)`	tangent

All trigonometric functions return values of type double precision.

Arguments are expressed in radians. To convert degrees to radians, use RADIANS.
asin and acos require arguments in the range -1 to 1. An out-of-range argument returns an error.
cot(0) returns Infinity.

Compute the cosine of an angle in radians.

Returns 1.

Combine pi with a trigonometric function.

Returns 1.
