Descripcion
The Math.asin()
method returns a numeric value between and radians for x
between -1 and 1. If the value of x
is outside this range, it returns NaN
.
Because asin()
is a static method of Math
, you always use it as Math.asin()
, rather than as a method of a Math
object you created (Math
is not a constructor).
Ejemplos
Usando Math.asin()
Math.asin(-2); // NaN
Math.asin(-1); // -1.5707963267948966 (-pi/2)
Math.asin(0); // 0
Math.asin(0.5); // 0.5235987755982989
Math.asin(1); // 1.5707963267948966 (pi/2)
Math.asin(2); // NaN
For values less than -1 or greater than 1, Math.asin()
returns NaN
