Python 3 - Number asin() Method


Advertisements

Description

The asin() method returns the arc sine of x (in radians).

Syntax

Following is the syntax for the asin() method −

asin(x)

Note − This function is not accessible directly, so we need to import the math module and then we need to call this function usingthe 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 'math domain error'.

Return Value

This method returns arc sine of x, in radians.

Example

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

#!/usr/bin/python3
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))

Output

When we run the above program, it produces the following result −

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