Math library does not match that of Python's

[JJtan2002]

The Math library currently has the same implementation as Source, following JavaScript. For reference:
https://docs.sourceacademy.org/MATH/

Instead, we should support all functions in the Python Math library as given here:
https://docs.python.org/3/library/math.html

Yes, correct. We need to support Python's math library.
