Built-In Functions and Syntax › Arc Sine

Arc Sine

The arc sine functions return the arc sine of a numeric value that represents an angle in either degrees or radians.

The single operand returned expresses the angle accurate to 10 decimal places in the range -90 to +90 for degrees and -p/2 to +p/2 for radians.

ARCSINDEG          ARCSINRAD
ARCSINE-DEGREES    ARCSINE-RADIANS

Parameters:

(value)

Specifies the numeric value representing the angle, in degrees or radians, whose arc sine is calculated. Value must be a value ranging from -1 to +1.

Example:

This example calculates the arc sine (in degrees) of 0.8660:

compute 'Arc Sine' = asind(0.8660)

  Arc Sine = 5.99971
