The math and cmath functions take their parameters in radians, but there is nothing stating this. The closest is "The math module consists mostly of thin wrappers around the platform C math library functions.". For starters, are we guaranteed that the platform math functions take radians?
Logged In: YES user_id=31435 I checked in a major rewrite of the math module docs, as Doc/lib/libmath.tex revision 1.32. This stuffed in "radians" as appropriate (among other things). Note that the function docstrings already told the radiaion story; e.g., >>> print math.cos.__doc__ cos(x) Return the cosine of x (measured in radians). >>> I didn't change the cmath docs, and don't intend to. Anyone using complex "angles" who doesn't already know they're working in radians shouldn't be allowed to import cmath <0.6 wink>.
Logged In: YES user_id=31435 Well, if I refuse to change cmath docs, chances are nobody else will, so closing this . The math module docs were changed.
