D toc

Excerpt

For input values between -1 and 1 inclusive, this function returns the angle in radians whose sine value is the input. This function is the inverse of the sine function. The value can be a Decimal or Integer literal or a reference to a column containing numeric values.

Info

NOTE: While this function returns values outside of the range -1 <= x <= 1, those values are not considered valid.

For more information on the sine function, see SIN Function.

Arc cosecant:

The arc secant function is computed as follows:

Input RangeOutput computation
x<=-1`asin(1/x)`
x>=1`asin(1/x)`
-1<x<1Not valid

D s lang vs sql

D s
snippet Basic

Numeric literal example:

D lang syntax
RawWrangle true ref true derive type:single value: asin(0.5)

asin(0.5)

Output: Returns the computation of the arc sine of 0.5. Output value is in radians.

Column reference example:

D lang syntax
RawWrangle true ref true derive type:single value: asin(X) as: asinX'

asin(X)

Output: Returns the arc sine of the values in `X` column.

snippet Syntax

D lang syntax
RawWrangle true syntax true derive type:single value: asin(numeric_value)

asin(numeric_value)

ArgumentRequired?Data TypeDescription
numeric_valueYstring, decimal, or integerName of column, Decimal or Integer literal, or function returning those types to apply to the function

D s lang notes

numeric_value

Name of the column, Integer or Decimal literal, or function returning that data type to apply to the function.

• Missing input values generate missing results.
• Literal numeric values should not be quoted. Quoted values are treated as strings.
• Multiple columns and wildcards are not supported.
