    I'm trying to evaluate arccot(0) but I can't find an approach that doesn't result in a divide by zero error. My math book seems to think it is possible (it says arccot(0) equals pi/2) but no matter how I try to evaluate it manually or on a calculator, it phails miserably.

    This is my procedure:
    Code:
    arccot 0 = ?
    cot ? = 0
    tan ? = 1/0
    EXCEPT YOU CAN'T EVALUATE 1/0!!!

    The whole idea of trig as well other math higher math courses is that you don't rely solely on a calculator because doing it by calculator ends up being too slow or just plain wrong.

    Where you messed up is at the cot part.

    cot ? = 0

    cos ?/sin ? = 0

    cos ? = 0

    ? = pi/2
