temporian.EventSet.arccos

arccos() -> EventSetOrNode

Calculates the inverse cosine of an EventSet's features.

Can only be used on floating point features.

Example

>>> a = tp.event_set(
...     timestamps=[1, 2, 3],
...     features={"M": [1.0, 0, -1.0]},
... )
>>> a.arccos()
indexes: ...
        timestamps: [1. 2. 3.]
        'M': [0.     1.5708 3.1416]
...

Returns:
