# Python – math.sinh() function

• Last Updated : 28 May, 2020

Math module contains a number of functions which is used for mathematical operations. The math.sinh() function returns the hyperbolic sine value of a number.

Syntax: math.sinh(x)

Parameter:This method accepts only single parameters.

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

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

Below examples illustrate the use of above function:

Example 1:

 `# Python code to implement``# the sinh()function``       ` `# importing "math"``# for mathematical operations  ``import` `math  ``      ` `a ``=` `math.pi ``/` `6``       ` `# Return the hyperbolic cosine value of numbers ``print` `(math.sinh(``7``))``print` `(math.sinh(``56``))``print` `(math.sinh(``2.45``))``print` `(math.sinh(``1``))`

Output:

```548.3161232732465
1.045829748006498e+24
5.75102656636201
1.1752011936438014
```

Example 2:

 `# Python code implementation of ``# the sinh() function``import` `math ``import` `numpy as np ``import` `matplotlib.pyplot as plt  ``    ` `in_array ``=` `np.linspace(``1``, np.pi``*``*``2``, ``30``) ``    ` `out_array ``=` `[] ``    ` `for` `i ``in` `range``(``len``(in_array)): ``    ``out_array.append(math.sinh(in_array[i])) ``    ``i ``+``=` `1``     ` `print``(``"Input_Array : \n"``, in_array)  ``print``(``"\nOutput_Array : \n"``, out_array)  ``  ` `  ` `plt.plot(in_array, out_array, ``"go-"``)  ``plt.title(``"math.sinh()"``)  ``plt.xlabel(``"X"``)  ``plt.ylabel(``"Y"``)  ``plt.show() `

Output:
