Python cmath.asinh() Method with Examples

cmath.asinh() Method in Python:

The cmath.asinh() method returns a number’s inverse hyperbolic sine.

There are primarily two types of branch cuts:

1. Extend from 1j along the imaginary axis to ∞ j to the right.
2. Extending from -1j to -∞ j to the left along the imaginary axis

Syntax:

cmath.asinh(x)

Parameters

x: This is Required. The number used to calculate the inverse hyperbolic sine of

Return Value:

Returns a complex value that represents the complex number’s inverse hyperbolic sine.

Examples:

Example1:

Input:

Given Complex Number = 3+4j

Output:

The given complex number's (3+4j) inverse hyperbolic sine value = 
(2.2999140408792695+0.9176168533514787j)

Example2:

Input:

Given realpart = 5
Given imaginary part = 2

Output:

The given complex number's (5+2j) inverse hyperbolic sine value = 
(2.3830308809003258+0.374670804825527j)

Note: The above input format is for dynamic input.

cmath.asinh() Method with Examples in Python

• Using Built-in Functions (Static Input)
• Using Built-in Functions (User Input)

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.asinh() method that returns the given complex number’s inverse hyperbolic sine value.
• Store it in another variable.
• Print the inverse hyperbolic 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 = 3+4j
# Pass the given complex number as an argument to the cmath.asinh() method that
# returns the given complex number's inverse hyperbolic sine value.
# Store it in another variable.
rslt = cmath.asinh(complexnumb)
# Print the inverse hyperbolic sine value of the given complex number.
print("The given complex number's", complexnumb,
      "inverse hyperbolic sine value = ")
print(rslt)

Output:

The given complex number's (3+4j) inverse hyperbolic sine value = 
(2.2999140408792695+0.9176168533514787j)

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.asinh() method that returns the given complex number’s inverse hyperbolic sine value.
• Store it in another variable.
• Print the inverse hyperbolic 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.asinh() method that
# returns the given complex number's inverse hyperbolic sine value.
# Store it in another variable.
rslt = cmath.asinh(complexnumb)
# Print the inverse hyperbolic sine value of the given complex number.
print("The given complex number's", complexnumb,
      "inverse hyperbolic sine value = ")
print(rslt)

Output:

Enter real part and complex part of the complex number = 5 2
The given complex number's (5+2j) inverse hyperbolic sine value = 
(2.3830308809003258+0.374670804825527j)
