numpy.arcsin() in Python

numpy.arcsin(x[, out]) = ufunc 'arcsin') : This mathematical function helps user to calculate inverse sine for all x(being the array elements). Parameters :

array : [array_like]elements are in radians.
out : [array_like]array of same shape as x.

Return :

An array with inverse sine of x
for all x i.e. array elements. 

The values are in the closed interval [-pi/2, pi/2].

  Code #1 : Working Output :
