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
to
. 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
