RE: bug in arccotangent function
I'm a physicist, not a mathematician, I have a very practical look at this problem :-)

cot(-pi/4) equals cot(3pi/4) = -1

therefore, arccot(-1) has many solutions, among many others the above mentioned two.
And yes: cot() ist periodic and (for a physicist) arccot() ist not a one-to-one relation.
