Math module contains a number of functions which is used for mathematical operations. The math.atanh() function returns the hyperbolic arctangent of a number as a value. The value passed in this function should be between -0.99 to 0.99.
Syntax: math.atanh(x)
Parameter:This method accepts only single parameters.
- x :This parameter is the value to be passed to atanh()
Returns:This function returns the hyperbolic arctangent of a number as a value.
Below examples illustrate the use of above function:
Example 1:
# Python code to implement # the atanh()function # importing "math" # for mathematical operations import math
# Return the hyperbolic arctangent of numbers print (math.asinh( 0.17 ))
print (math.asinh( 0.56 ))
print (math.asinh( 0.245 ))
print (math.asinh( - 0.3445 ))

Example 2:
# Python code to implement # the atanh()function import math
import numpy as np
import matplotlib.pyplot as plt
in_array = np.linspace( - np.pi / 3.5 , np.pi / 3.5 , 10 )
print ( "Input_Array : \n" , in_array)
out_array = []
for i in range ( len (in_array)):
out_array.append(math.atanh(in_array[i]))
i + = 1
print ( "\nOutput_Array : \n" , out_array)
plt.plot(in_array, out_array, "go:" )
plt.title( "math.atanh()" )
plt.xlabel( "X" )
plt.ylabel( "Y" )
plt.show() |
