The tensorflow.math
module provides support for many basic mathematical operations. The tf.acos ()
[alias tf.math.acos
] function provides support for the inverse cosine 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 inverse cosine is calculated for each element.
Syntax : tf.acos (x, name = None) or tf.math .acos (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.
