ASIN(X)

Description
This function returns the arc sine of angle X. The result is the angle (in radians) whose sine is X and ranges from to . To convert the result from radians to degrees, use the DEGREES function.

Parameters
X
A numeric value between -1 and 1

Examples
ASIN(0) = 0

ASIN(A2) = 1.570796327
where A2 = 1

DEGREES(ASIN(V7)) = -11.536959
where V7 = -0.2

ASIN(30) = Error - ASIN, domain is -1 <= x <= 1
