Trigonometric inverse cosine, element-wise.
tf.keras.ops.arccos(
x
)
The inverse of cos so that, if y = cos(x), then x = arccos(y).
Returns |
|---|
Tensor of the angle of the ray intersecting the unit circle at the given
x-coordinate in radians [0, pi].

Example:
x = keras.ops.convert_to_tensor([1, -1])
keras.ops.arccos(x)
array([0.0, 3.1415927], dtype=float32)
