Parameter |
Description |
value |
The sine of an angle; that is, the ratio of
the adjacent side to the hypotenuse. See below for special cases. |
Return value |
Description |
double |
The inverse sine of the parameter in radians.
See rad (JavaScript) to
convert degrees to radians. |
Usage
Special cases are as follows:
- The inverse sine of
NaN
or an absolute value
greater than 1 is NaN.
- The inverse sine of
+0
is positive zero.
- The inverse sine of
-0
is negative zero.
