Numpy arcsin() method

Last Updated : 17 Mar 2025

This function is used to calculate the inverse sin of the array elements.

Syntax

Parameters

array: these are the array elements of which, the inverse sin values are to be calculated.
Out: It is the shape of the output array.

Return

It returns an array containing the inverse sin for all the array elements, x.

Example

import numpy as np 
import math

arr = [0, 0.3, -1] 
print ("Input array : \n", arr) 

arcsine = np.arcsin(arr) 
print ("\nInverse Sine values : \n", arcsine) 

Output:

Input array : 
 [0, 0.3, -1]

Inverse Sine values : 
 [ 0.          0.30469265 -1.57079633]
