# Python Number asin() Function

## Description:

This function returns the arc sine of x, in radians.

## Syntax:

    asin(x)

Note: This function is not accessible directly so we need to import math module and then we need to call this function using math static object.

## Parameters:

Here is the detail of parameters:

- x: Must be a numeric value in the range -1 to 1. If x is greater than 1 then it will generate an error.

## Return Value:

The arc sine of x, in radians.

## Example:

    #!/usr/bin/python
    import math

    print "asin(0.64) : ",  math.asin(0.64)
    print "asin(0) : ",  math.asin(0)
    print "asin(-1) : ",  math.asin(-1)
    print "asin(1) : ",  math.asin(1)

This will produce following result:

    asin(0.64) :  0.694498265627
    asin(0) :  0.0
    asin(-1) :  -1.57079632679
    asin(1) :  1.57079632679
