Syntax:
ASIN(number)
Description:
The ASIN function (arcsine) is the inverse function of the SIN function: It returns the inverse sine of a number – that is, the angle whose sine is the Number.
Number must lie within the range from -1 to 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.
