   summary: "Computes acos of x element-wise."
-  description: <<END
-Given a tensor `x`, this operation returns a tensor containing the 
-arccosine of each element in `x` or in other words it returns the 
-inverse of cos of the value.
-
-For Example :
-
->>> x = tf.constant([1,0], dtype=tf.float16) 
->>> tf.math.acos(x)
-<tf.Tensor: shape=(2,), dtype=float16, numpy=array([0.  , 1.57], dtype=float16)>
