tf.math.acos(
    x, name=None
)

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].

For example:

x = tf.constant([1.0, -0.5, 3.4, 0.2, 0.0, -2], dtype = tf.float32)
tf.math.acos(x)
<tf.Tensor: shape=(6,), dtype=float32,
numpy= array([0. , 2.0943952, nan, 1.3694383, 1.5707964, nan],
dtype=float32)>

Args
x	A Tensor. Must be one of the following types: bfloat16, half, float32, float64, uint8, int8, int16, int32, int64, complex64, complex128.
name	A name for the operation (optional).

Returns
A Tensor. Has the same type as x.
