The Python asin function calculates the trigonometry Arc Sine for the specified expression. The asin or Arc Sine is also called the inverse of a Sine. In this section, we discuss how to use Python asin function with examples.
The syntax of the Python asin Function is
math.asin(number);
Number: A valid numerical expression to find the Arc Sine value.
- If the number argument is a positive or negative number, the asin function returns the Arc Sine value.
- If it is not a number, the asin function returns TypeError.
- And if it is outside the range -1 and 1, the asin function returns ValueError.
Python asin Function Example
The asin Function allows you to find the trigonometry Arc Sine for the numeric values. In this asin example, we will find the Arc Sine values of different data types and display the output.
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'))
First, we used the Python asin Function directly on both Positive integer and negative integer. The following statements 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 Tuple and List items. If you see the screenshot above, the asin function works 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 math 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 the asin Function on the String value, which returns TypeError.
print('Arc Sine value of String Value = ', math.asin('Python'))
