Computes acos of x element-wise.
tf.math.acos(
x, name=None
)
Used in the notebooks
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)>
