Syntax:
ASIN(Number)
Description:
Returns the arcsine of Number, i.e., the angle whose sine is Number.
Number must be > -1 and < 1.
The result is expressed in radians.
Example:
ASIN(1) returns 1.5708... (corresponds to PI()/2, thus 90°)
ASIN(SIN(0.1234)) returns 0.1234
Tip:
You can use the DEGREES function to convert the result from radians to degrees.
