Python - math.asinh() function

Last Updated : 28 May, 2020

Math module contains a number of functions which is used for mathematical operations. The math.asinh() function returns the hyperbolic arc sine value of a number.

Syntax: math.asinh(x) Parameter:This method accepts only single parameters.

x :This parameter is the value to be passed to asinh()

Returns:This function returns the hyperbolic arc sine value of a number.

Below examples illustrate the use of above function: Example 1:

Python3

# Python code to implement
# the asinh()function
       
# importing "math"
# for mathematical operations  
import math  
       
# Return the hyperbolic arc sine value of numbers 
print (math.asinh(17))
print (math.asinh(5.6))
print (math.asinh(245))
print (math.asinh(-3445))

Output:

3.5272244561999657
2.4237920435875173
6.194409556009931
-8.837826385072708

Example 2:

Python3

# Python code to implement
# the aasinh()function
import math 
import matplotlib.pyplot as plt  
  
in_array = [-0.14159265, -0.57039399, -0.28559933, 
            0.28559933, 0.57039399,  0.94159265] 
  
out_array = [] 
  
for i in range(len(in_array)): 
    out_array.append(math.asinh(in_array[i])) 
    i += 1
     
print("Input_Array : \n", in_array)  
print("\nOutput_Array : \n", out_array)   

plt.plot(in_array, out_array, "go:")  
plt.title("math.asinh()")  
plt.xlabel("X")  
plt.ylabel("Y")  
plt.show()

Output:

Input_Array : 
 [-0.14159265, -0.57039399, -0.28559933, 0.28559933, 0.57039399, 0.94159265]

Output_Array : 
 [-0.14112374861052449, -0.5432727660031201, -0.28185270483975433, 0.28185270483975433, 0.5432727660031201, 0.8394645626112472]
