temporian.EventSet.cos

cos() -> EventSetOrNode

Calculates the cosine of an EventSet's features.

Can only be used on floating point features.

Example

>>> a = tp.event_set(
...     timestamps=[1, 2, 3, 4, 5],
...     features={"M": [0, np.pi/3, np.pi/2, np.pi, 2*np.pi]},
... )
>>> a.cos()
indexes: ...
        timestamps: [1. 2. 3. 4. 5.]
        'M': [ 1.0000e+00  5.0000e-01  6.1232e-17 -1.0000e+00  1.0000e+00]
...

Returns:
