pymc.math.tan

pymc.math.tan = Elemwise(scalar_op=tan,inplace_pattern=<frozendict {}>)

tangent of a

Computes element-wise tangent of a tensor in radians.

Parameters:

aTensorLike

Input tensor in radians

Returns:

TensorVariable

Output tensor with the tangent of each element

Notes

This function corresponds to NumPy’s np.tan function. Tangent is undefined at π/2 + nπ where n is an integer.

Examples

>>> import pytensor
>>> import pytensor.tensor as pt
>>> import numpy as np
>>> x = pt.vector("x")
>>> f = pytensor.function([x], pt.tan(x))
>>> f([0, np.pi / 4, np.pi / 2 - 1e-10])  # Avoiding exact π/2 which is undefined
array([0.00000000e+00, 1.00000000e+00, 1.25655683e+10])
