atanh()

atanh(x) returns inverse hyperbolic tangent of x , the input number x is in radian.
import math
print(math.atanh(-0.9))  # -1.4722194895832204
print(math.atanh(0))     # 0.0
print(math.atanh(0.9))   # 1.4722194895832204
Note that all the inputs are in radian.
less than or equal to -1 or more than equal to 1 , we will get ValueError
import math
print(math.atanh(1.0))  
Above code will generate error.

Inputs in degree

We can convert radian value to degree and use the same
import math
in_degree = 50
in_redian = math.radians(in_degree)
print(math.atanh(in_redian)) # 1.344146641636003
Output
1.344146641636003
1 radian = 57.2957914331 degree
1 degree = 0.0174533 radian

Drawing graph of atanh()

We will use Matplotlib to generate graph of atanh atanh graph
import matplotlib.pyplot as plt
x=[]
y=[]
i=-0.99
while (i<1):
    x.append(i)
    y.append(math.atanh(i))
    i=i+0.01
plt.plot(x,y)
plt.axvline(x=0.00,linewidth=2, color='#f1f1f1')
plt.axhline(y=0.00,linewidth=2, color='#f1f1f1')
plt.grid(linestyle='-',
    linewidth=0.5,color='#f1f1f1')
plt.show()
