Python asin function

Python asin(x) function returns the Arcsine value of x. The principle values for x is [-1,1]. 

>>> import math
>>> math.asin(0.5)

0.5235987755982989

>>> math.asin(1)

1.5707963267948966

>>> math.asin(0)

0.0

Arcsin Functions
1. arcsin(-x) = -arcsin(x);
2. arcsin(x) + arccos(x) = π/2;

Arcsine function is the inverse of sine, arcsine(x)=sin-1(x). The principle values for x is [-1,1].
