updating oE arcsin


include math.e 
namespace math 
public function arcsin(trig_range x) 

returns an angle given its sine.

  1. value : an object, each atom in which will be acted upon.

An object, the same shape as value. When value is an atom, the result is an atom, an angle whose sine is value.


If any atom in value is not in the -1..1 range, it cannot be the sine of a real number, and an error occurs.


A value between -PI/2 and +PI/2 (radians) inclusive will be returned.

This function may be applied to an atom or to all elements of a sequence.

arcsin is not as fast as arctan.

Example 1:
s = arcsin({-1,0,1}) 
s is {-1.570796327, 0, 1.570796327}
