    tf.math.acosh(
        x: Annotated[Any, TV_Acosh_T], name=None
    ) -> Annotated[Any, TV_Acosh_T]

Given an input tensor, the function computes inverse hyperbolic cosine of every element.
Input range is `[1, inf]`. It returns `nan` if the input lies outside the range.

    x = tf.constant([-2, -0.5, 1, 1.2, 200, 10000, float("inf")])
    tf.math.acosh(x) ==> [nan nan 0. 0.62236255 5.9914584 9.903487 inf]
