Math module contains a number of functions which is used for mathematical operations. The math.acosh() function returns the hyperbolic arc cosine value of a number. The value passed in this function should be greater than or equal to 1.
Syntax: math.acosh(x)
Parameter:This method accepts only single parameters.
- x :This parameter is the value to be passed to acosh()
Returns:This function returns the hyperbolic arc cosine value of a number.
Below examples illustrate the use of above function:
Example 1:
# Python code to implement # the acosh()function # importing "math" # for mathematical operations import math a = math.pi / 6 # Return the hyperbolic arc cosine value of numbers print (math.acosh(7)) print (math.acosh(56)) print (math.acosh(2.45)) print (math.acosh(1)) |
Output:
2.6339157938496336 4.718419142372879 1.5447131178707394 0.0
Example 2:
# Python code implementation of # the acosh() function import math import numpy as np import matplotlib.pyplot as plt in_array = np.linspace(1, np.pi**2, 30) out_array = [] for i in range(len(in_array)): out_array.append(math.acosh(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.acosh()") plt.xlabel("X") plt.ylabel("Y") plt.show() |
