Python – tensorflow.math.cos()

• Last Updated : 17 Jun, 2021

TensorFlow is open-source python library designed by Google to develop Machine Learning models and deep learning  neural networks.
cos() is used to find element wise cos of x.

Syntax: tf.math.cos(x, name)

Parameters:

• x: It’s the input tensor. Allowed dtype for this tensor are bfloat16, half, float32, float64.
• name(optional): It’s defines the name for the operation.

Returns:  It returns a tensor of same dtype as x.

Example 1:

Python3

 `# Importing the library``import` `tensorflow as tf` `# Initializing the input tensor``a ``=` `tf.constant([ ``-``.``5``, ``-``.``3``, ``0``, .``3``, .``5``], dtype ``=` `tf.float64)` `# Printing the input tensor``print``(``'Input: '``, a)` `# Calculating tangent``res ``=` `tf.math.cos(x ``=` `a)` `# Printing the result``print``(``'Result: '``, res)`

Output:

```Input:  tf.Tensor([-0.5 -0.3  0.   0.3  0.5], shape=(5, ), dtype=float64)
Result:  tf.Tensor([0.87758256 0.95533649 1.         0.95533649 0.87758256], shape=(5, ), dtype=float64)```

Example 2: Visualization

Python3

 `# Importing the library``import` `tensorflow as tf``import` `matplotlib.pyplot as plt` `# Initializing the input tensor``a ``=` `tf.constant([``-``.``5``, ``-``.``3``, ``0``, .``3``, .``5``], dtype ``=` `tf.float64)` `# Calculating tangent``res ``=` `tf.math.cos(x ``=` `a)` `# Plotting the graph``plt.plot(a, res, color ``=``'green'``)``plt.title(``'tensorflow.math.cos'``)``plt.xlabel(``'Input'``)``plt.ylabel(``'Result'``)``plt.show()`
