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)
