ASIN

Applies to: Calculated column Calculated table Measure Visual calculation

Returns the arcsine, or inverse sine, of a number. The arcsine is the angle whose sine is number. The returned angle is given in radians in the range -pi/2 to pi/2.

Syntax

ASIN(number)  

Parameters

Term	Definition
number	The sine of the angle you want and must be from -1 to 1.

Return value

Returns the arcsine, or inverse sine, of a number.

Remarks

To express the arcsine in degrees, multiply the result by 180/PI( ) or use the DEGREES function.

Example

Formula	Description	Result
= ASIN(-0.5)	Arcsine of -0.5 in radians, -pi/6	-0.523598776
= ASIN(-0.5)*180/PI()	Arcsine of -0.5 in degrees	-30
= DEGREES(ASIN(-0.5))	Arcsine of -0.5 in degrees	-30
