pymc.math.sin

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

sine of a

Computes element-wise sine of a tensor in radians.

Parameters:

aTensorLike

Input tensor in radians

Returns:

TensorVariable

Output tensor with the sine of each element

Notes

This function corresponds to NumPy’s np.sin function.

Examples

>>> import pytensor
>>> import pytensor.tensor as pt
>>> import numpy as np
>>> x = pt.vector("x")
>>> f = pytensor.function([x], pt.sin(x))
>>> f([0, np.pi / 2, np.pi])
array([ 0.00000000e+00,  1.00000000e+00,  1.22464680e-16])
