I'll note that SciPy actually does have `sinpi` and `cospi`-they just happen to be private:
https://github.com/scipy/scipy/blob/master/scipy/special/functions.json#L58 https://github.com/scipy/scipy/blob/master/scipy/special/functions.json#L12
They are used extensively inside the module though as helpers in other special functions and have extensive tests of their own:
https://github.com/scipy/scipy/blob/master/scipy/special/tests/test_mpmath.p...
https://github.com/scipy/scipy/blob/master/scipy/special/tests/test_mpmath.p...
https://github.com/scipy/scipy/blob/master/scipy/special/tests/test_mpmath.p...
https://github.com/scipy/scipy/blob/master/scipy/special/tests/test_mpmath.p...
I have no objections to making them public; the PR is as simple as removing the underscores and adding a docstring.
