The tensorflow.math module provides support for many basic mathematical operations. The tf.acosh () [alias tf.math.acosh ] function provides support for the inverse hyperbolic cosine function in Tensorflow … It expects input in the range [1, ∞) and returns nan for any input outside this range. Input type — tensor, and if the input contains more than one element, the element-wise inverse hyperbolic cosine is calculated.

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

# Library import Tensorflow import tensorflow as tf   # Constant vector of size 6 a = tf.constant ([ 1.0 , 0.5 , 3.4 , - 2.1 , 0.0 , 6.5 ],   dtype = tf.float32)   # Applying acosh and # save the result to & # 39; b & # 39; b = tf.acosh (a, name = `acosh` )    # 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: 0", shape = (6,) , dtype = float32) Input: [1. 0.5 3.4 -2.1 0. 6.5] Return type: Tensor ("acosh: 0", shape = (6,), dtype = float32) Output: [0. nan 1.894559 nan nan 2.558979]

# Library import Tensorflow import tensorflow as tf   # Importing the NumPy library import numpy as np   # Import function matplotlib.pylot import matplotlib.pyplot as plt   # Vector size 15 with values ​​from 1 to 10 a = np.linspace ( 1 , 10 , 15 )   # Applying inverse hyperbolic cosine # function and saving the result to & # 39; b & # 39; b = tf.acosh (a, name = `acosh` )    # Initiating a Tensorflow session with tf.Session () as sess: print ( `Input:` , a) print ( `Output:` , sess.run (b)) plt.plot (a, sess.run (b), color = `red` , marker = "o" )  plt.title ( "tensorflow.acosh" )  plt.xlabel ( "X" )  plt.ylabel ( "Y" )    plt.show ()
