The ** cosh() function** returns the hyperbolic cosine of a number. To be more specific, it returns the hyperbolic cosine of a number in the radians.

Figure 1 shows the mathematical representation of the `cosh()`

function.

Note: The

`math`

module is required for this function.

```
cosh(num)
```

This function requires a `number`

that represents an `angle`

in `radians`

as a parameter.

In order to convert `degrees`

to `radians`

, use the following formula:

```
radians = degrees * ( pi / 180.0 )
```

`cosh()`

returns the `hyperbolic cosine`

of a number `(radians)`

that is sent as a parameter.

import math #positive number in radians print "The value of cosh(2.3) : ", math.cosh(2.3) #negative number in radians print "The value of cosh(-2.3) : ", math.cosh(-2.3) #converting the degrees angle into radians and then applying cosh() #degrees = 180 #PI = 3.14159265 result = 180.0 * (math.pi / 180.0) print "The value of cosh("+str(result)+") : ", math.cosh(result)
