ASIN function

Description

Arcsine function. ASIN(x) returns the arcsine of x. The arcsine function is the inverse function of the sine function and calculates the angle for a given sine. X must be in the range [-1..1]. The result is an angle expressed in radians. To convert from radians to degrees, use the DEGREES function.

Examples

ASIN(0) equals 0

ASIN(1) equals 1.5707963 (=PI/2)

DEGREES(ASIN(1)) equals 90
