Python's number is the sin of 32 radians which is the same as the sin
of 0.584 radians. Microsoft's is the sin of 32 degrees which is 0.558
radians, so the results are coincidentally fairly close to one
another. Math libraries usually take args in radians while
calculators usually let you select between radians and degrees.

Same thing.
