Computes acos of x element-wise.

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 range is [-1, 1] and the output has a range of [0, pi].

x A Tensor. Must be one of the following types: bfloat16, half, float32, float64, int8, int16, int32, int64, complex64, complex128.
name A name for the operation (optional).

A Tensor. Has the same type as x.
