ASIN

Syntax: ASIN(X)

X = a numeric value between -1 and 1.

ASIN returns the arc sine of angle X. The result is the angle (in radians) whose sine is X and ranges from $\pi/2$ to $-\pi/2$. To convert the result from radians to degrees, use the DEGREES function.

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
