How to calculate arcsine in Python

To find the arcsin (arcsin) in Python use the asin() function of the math module.

from math import asin
asin(x)

The parameter x is the value of the sine of an angle θ measured in radians.

The asin() function outputs the inverse sine function

What is the arcsin? It is the inverse trigonometric function of the sine arcsin=sin^-1. The function finds the amplitude of the angle that determines a particular sine value.

Examples

Example 1

Given a sine sin θ = 0.5, find the angle θ which determines it.

>>> from numpy import asin
>>> x=0.50
>>> asin(x)

The output of the asin() function is as follows

0.5235987755982989

It is the measure of the arc on the circumference in radians (angle θ) that determines the value sin θ = 0.5.

The angle θ measures 0.5235987755982989 (approximately 30 °).

Verify

To verify the result just obtained, it is necessary to calculate the sine of the angle 0.5235987755982989

>>> from numpy import sin
>>> x= 0.5235987755982989
>>> sin(x)

The result of the sin() function is as follows:

0.5
