Syntax

Following is the syntax for asin() method −

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

• x − This 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

This method returns arc sine of x, in radians.

Example

The following example shows the usage of asin() method.

Live Demo

#!/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)

When we run above program, it produces following result −

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