Python - cmath.cosh() function

cMath module contains a number of functions which is used for mathematical operations for complex numbers. The cmath.cosh() function returns the hyperbolic cosine value of a complex number. The value passed in this function can be int, float, and complex numbers.

Syntax: cmath.cosh(x)

Parameter:This method accepts only single parameters.

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

Returns:This function returns the hyperbolic cosine value of a complex number.

Below examples illustrate the use of above function:

Example #1 : In this example we can see that by using cmath.cosh() method, we are able to get the values of hyperbolic cosine by passing any value to it.

# Python code to implement
# the cosh()function
      
# importing "cmath"
# for mathematical operations  
import cmath 
  
# using cmath.cosh() method 
val = cmath.cosh(3) 
  
print(val) 

Output:

(10.067661995777765+0j)

Example 2:

# Python code to implement
# the cosh()function
      
# importing "cmath"
# for mathematical operations  
import cmath 
  
# using cmath.cosh() method 
val = cmath.cosh(2 + 5j) 
  
print(val) 

Output:

(2.37054853731792+1.184231684275022j)
