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 cosineby passing any value to it.

Output:

(10.067661995777765+0j)

Example 2:

Output:

(2.37054853731792+1.184231684275022j)
