Learn the RESHADED framework for architecting web-scale applications by determining requirements, constraints, and assumptions before diving into a step-by-step design process.

The sinh() function returns the hyperbolic sine of a number. To be more specific, it returns the hyperbolic sine of a number in radians.

The figure below shows the mathematical representation of the sinh() function.

Note: The math module is required for this function.

## Syntax

sinh(num)


## Parameter

This function requires a number that represents an angle in radians as a parameter.

The following formula is used to convert degrees to radians.

radians = degrees * ( pi / 180.0 )


## Return value

sinh() returns a number’s hyperbolic sine (radians), which is sent as a parameter.

## Example

import math#positive number in radiansprint "The value of sinh(2.3): ",  math.sinh(2.3)#negative number in radiansprint "The value of sinh(-2.3): ",  math.sinh(-2.3)#converting the degrees angle into radians and then applying sinh()#degrees = 90#PI = 3.14159265result = 90.0 * (math.pi / 180.0)print "The value of sinh("+str(result)+"): ",  math.sinh(result)
