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

your calculator cant handle the power of infinity.
