Python | Tensorflow asin () method

The tensorflow.math module provides support for many basic mathematical operations. The tf.asin () [alias tf.math.asin ] function provides support for the inverse sine function in Tensorflow. The input is assumed to be in the range [-1, 1] and outputs the output in radians. Returns nan, if the input is not in the range [-1, 1]. Input type — tensor, and if the input contains more than one element, the elementwise inverse sine is calculated.

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

Parameters :
x : A tensor of any of the following types: bfloat16, half, float32 , float64, int32, int64, complex64, or complex128.
name (optional): The name for the operation.

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

Code # 1:

# Import Tensorflow Library import tensorflow as tf   # Constant vector of size 6 a = tf.constant ([ 1.0 , - 0.5 , 3.4 , 0.2 , 0.0 , - 2 ], dtype = tf.float32)    # Using asin and # save the result to & # 39; b & # 39; b = tf.asin (a, name = ’ asin’ )    # 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: Ten sor ("Const_6: 0", shape = (6,), dtype = float32) Input: [1. -0.5 3.4 0.2 0. -2. ] Return type: Tensor ("asin_2: 0", shape = (6,), dtype = float32) Output: [1.5707964 -0.5235988 nan 0.20135793 0. nan]
