Python ASIN

by

The Python ASIN function is one of the Python Math function which is used to calculate the trigonometry Arc Sine for the specified expression. Arc Sine is also called as inverse of a Sine, Please refer Python SIN Function article to understand the Sine Function. In this article we will show you, How to use ASIN() function in Python Programming language with example.

Syntax of a Python ASIN Function

The basic syntax of the ASIN Function in Python Programming Language is as shown below:

Math.asin(number);

Number: It can be a number or a valid numerical expression for which you want to find Arc Sine value.

  • If the number argument is positive or negative number, ASIN() function will return the Arc Sine value.
  • If the number argument is not a number, ASIN() function will return TypeError.
  • If the number argument is outside the range -1 and 1, ASIN() function will return ValueError.

Python ASIN Function Example

The Python ASIN Function allows you to find the trigonometry Arc Sine for the numeric values. In this example, We are going to find the Arc Sine values of different data types and display the output

PYTHON CODE

# Python ASIN Function

import math

Tup = (0.21, 0.12, 0.39, -0.89 , 0.42) # Tuple Declaration
Lis = [-0.1, 0.92, 0.35, -0.46 , 0.85] # List Declaration

print('Arc Sine value of Positive Number = %.2f' %math.asin(1))
print('Arc Sine value of Negative Number = %.2f' %math.asin(-1))

print('Arc Sine value of Tuple Item = %.2f' %math.asin(Tup[3]))
print('Arc Sine value of List Item = %.2f' %math.asin(Lis[2]))

print('Arc Sine value of Multiple Number = %.2f' %math.asin(0.10 + 0.20 - 0.40))
print('Arc Sine value of String Value = ', math.asin('Python'))

OUTPUT

Python ASIN Function

ANALYSIS

First, We declared Python List and Tuple with some random values. Next, We used the ASIN() Function directly on both the Positive integer and negative integer. Following statements will find the Arc Sine of the corresponding values.

print('Arc Sine value of Positive Number = %.2f' %math.asin(1))
print('Arc Sine value of Negative Number = %.2f' %math.asin(-1))

Next, We used the ASIN() Function on Python Tuple and List items. If you observe the above screenshot, ASIN() function is working perfectly on them.

print('Arc Sine value of Tuple Item = %.2f' %math.asin(Tup[3]))
print('Arc Sine value of List Item = %.2f' %math.asin(Lis[2]))

Next, We used the ASIN() Function directly on multiple values.

print('Arc Sine value of Multiple Number = %.2f' %math.asin(0.10 + 0.20 - 0.40))

Within the last statement, We tried ASIN() Function on String value. As we said before, this will return TypeError as output

print('Arc Sine value of String Value = ', math.asin('Python'))
