Fix trigonometric function's output when input is inf

[Kaida-Amethyst]

There are some problems:

sin(inf) should be NaN, not Infinity
sin(-inf) should be NaN, not -Infinity
cos(inf) should be NaN, not Infinity
cos(-inf) should be NaN, not -Infinity
tan(inf) should be NaN, not Infinity
tan(-inf) should be NaN, not -Infinity
asin(inf) should be NaN, not Infinity
asin(-inf) should be NaN, not -Infinity
acos(inf) should be NaN, not Infinity
acos(-inf) should be NaN, not -Infinity

Verify it in python (Not only python, I get same resutlt in C, rust, and the like):

>>> import numpy as np
>>> import warnings
>>> warnings.simplefilter("ignore") # ignore warnings because numpy will throw warnings when output contains `nan`
>>> numbers_contain_inf = np.array([-np.inf, np.inf, 0.0, 1.0])
>>> np.sin(numbers_contain_inf)
array([       nan,        nan, 0.        , 0.84147098])
>>> np.cos(numbers_contain_inf)
array([       nan,        nan, 1.        , 0.54030231])
>>> np.tan(numbers_contain_inf)
array([       nan,        nan, 0.        , 1.55740772])
>>> np.arcsin(numbers_contain_inf)
array([       nan,        nan, 0.        , 1.57079633])
>>> np.arccos(numbers_contain_inf)
array([       nan,        nan, 1.57079633, 0.        ])
>>>
