# Python | Tensorflow sinh() method

• Last Updated : 10 Jan, 2022

Tensorflow is an open-source machine learning library developed by Google. One of its applications is to develop deep neural networks.

The module `tensorflow.math` provides support for many basic mathematical operations. Function `tf.sinh()` [alias `tf.math.sinh`] provides support for the hyperbolic sine function in Tensorflow. It expects the input in radian form. The input type is tensor and if the input contains more than one element, element-wise hyperbolic sine is computed.

Syntax: tf.sinh(x, name=None) or tf.math.sinh(x, name=None)

Parameters:
x: A tensor of any of the following types: float16, float32, float64, complex64, or complex128.
name (optional): The name for the operation.

Return type: A tensor with the same type as that of x.

Code #1:

## Python3

 `# Importing the Tensorflow library``import` `tensorflow as tf`` ` `# A constant vector of size 6``a ``=` `tf.constant([``1.0``, ``-``0.5``, ``3.4``, ``-``2.1``, ``0.0``, ``-``6.5``],``                               ``dtype ``=` `tf.float32)`` ` `# Applying the sinh function and``# storing the result in 'b'``b ``=` `tf.sinh(a, name ``=``'sinh'``)`` ` `# Initiating a Tensorflow session``with tf.Session() as sess:``    ``print``(``'Input type:'``, a)``    ``print``(``'Input:'``, sess.run(a))``    ``print``(``'Return type:'``, b)``    ``print``(``'Output:'``, sess.run(b))`

Output:

```Input type: Tensor("Const_3:0", shape=(6, ), dtype=float32)
Input: [ 1.  -0.5  3.4 -2.1  0.  -6.5]
Return type: Tensor("sinh:0", shape=(6, ), dtype=float32)
Output: [   1.1752012   -0.5210953   14.965365    -4.0218563    0.
