Acos

`
#include <math_ops.h>
`


Computes acos of x element-wise.

## Summary


Provided an input tensor, the
`
tf.math.acos
`
operation returns the inverse cosine of each element of the tensor. If
`
y = tf.math.cos(x)
`
then,
`
x = tf.math.acos(y)
`
.


[Input](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)
range is
`
[-1, 1]
`
and the output has a range of
`
[0, pi]
`
.


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />


Returns:

- `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output
  ` : The y tensor.
