# Python – math.asinh() function

• Last Updated : 28 May, 2020

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

Syntax: math.asinh(x)

Parameter:This method accepts only single parameters.

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

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

Below examples illustrate the use of above function:

Example 1:

 `# Python code to implement``# the asinh()function``        ` `# importing "math"``# for mathematical operations  ``import` `math  ``        ` `# Return the hyperbolic arc sine value of numbers ``print` `(math.asinh(``17``))``print` `(math.asinh(``5.6``))``print` `(math.asinh(``245``))``print` `(math.asinh(``-``3445``))`

Output:

```3.5272244561999657
2.4237920435875173
6.194409556009931
-8.837826385072708
```

Example 2:

 `# Python code to implement``# the aasinh()function``import` `math ``import` `matplotlib.pyplot as plt  ``   ` `in_array ``=` `[``-``0.14159265``, ``-``0.57039399``, ``-``0.28559933``, ``            ``0.28559933``, ``0.57039399``,  ``0.94159265``] ``   ` `out_array ``=` `[] ``   ` `for` `i ``in` `range``(``len``(in_array)): ``    ``out_array.append(math.asinh(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.asinh()"``)  ``plt.xlabel(``"X"``)  ``plt.ylabel(``"Y"``)  ``plt.show()  `

Output:

```Input_Array :
[-0.14159265, -0.57039399, -0.28559933, 0.28559933, 0.57039399, 0.94159265]

Output_Array :
[-0.14112374861052449, -0.5432727660031201, -0.28185270483975433, 0.28185270483975433, 0.5432727660031201, 0.8394645626112472]
