cmath.asin() Method in Python:
The cmath.asin() method returns the complex number’s arc sine.
There are two types of branch cuts:
- Extends right from 1 to ∞ along the real axis.
- Extends left along the real axis from -1 to -∞
Syntax:
cmath.asin(x)
Parameters
x: This is Required. A number that can be used to calculate the arc sine of
Return Value:
Returns a complex value that represents the complex number’s arc sine.
Examples:
Example1:
Input:
Given Complex Number = 4+2j
Output:
The given complex number's (4+2j) arc sine value = (1.096921548830143+2.183585216564564j)
Example2:
Input:
Given realpart = 5 Given imaginary part = 2
Output:
The given complex number's (5+2j) arc sine value = (1.184231684275022+2.37054853731792j)
Note: The above input format is for dynamic input.
cmath.asin() Method with Examples in Python
Method #1: Using Built-in Functions (Static Input)
Approach:
- Import cmath module(for complex number operations) using the import keyword.
- Give the complex number as static input and store it in a variable.
- Pass the given complex number as an argument to the cmath.asin() method that returns the given complex number’s arc sine value.
- Store it in another variable.
- Print the arc sine value of the given complex number.
- The Exit of the Program.
Below is the implementation:
# Import cmath module(for complex number operations) using the import keyword. import cmath # Give the complex number as static input and store it in a variable. complexnumb = 4+2j # Pass the given complex number as an argument to the cmath.asin() method that # returns the given complex number's arc sine value. # Store it in another variable. rslt = cmath.asin(complexnumb) # Print the arc sine value of the given complex number. print("The given complex number's", complexnumb, "arc sine value = ") print(rslt)
Output:
The given complex number's (4+2j) arc sine value = (1.096921548830143+2.183585216564564j)
Method #2: Using Built-in Functions (User Input)
Approach:
- Import cmath module(for complex number operations) using the import keyword.
- Give the real part and imaginary part of the complex number as user input using map(), int(), split().
- Store it in two variables.
- Using a complex() function convert those two variables into a complex number and store it in a variable.
- Pass the given complex number as an argument to the cmath.asin() method that returns the given complex number’s arc sine value.
- Store it in another variable.
- Print the arc sine value of the given complex number.
- The Exit of the Program.
Below is the implementation:
# Import cmath module(for complex number operations) using the import keyword. import cmath # Give the real part and imaginary part of the complex number as user input # using map(), int(), split(). # Store it in two variables. realnumb, imaginarynumb = map(int, input( 'Enter real part and complex part of the complex number = ').split()) # Using a complex() function convert those two variables into a complex number. complexnumb = complex(realnumb, imaginarynumb) # Pass the given complex number as an argument to the cmath.asin() method that # returns the given complex number's arc sine value. # Store it in another variable. rslt = cmath.asin(complexnumb) # Print the arc sine value of the given complex number. print("The given complex number's", complexnumb, "arc sine value = ") print(rslt)
Output:
Enter real part and complex part of the complex number = 5 2 The given complex number's (5+2j) arc sine value = (1.184231684275022+2.37054853731792j)
