.Asin()
The Math.Asin() method computes an angle in radians whose sine is a specified number. In Math, this is known as the inverse sine function.
Syntax
Math.Asin(value);
value
is the input value of type double, which must be in the range -1 <= value
<= 1.
Returns an angle measured in radians, of type double
, whose sine is value
. If an invalid value is passed to the function, or no value is passed at all, NaN
is returned.
