  1. wouldn't it depend on the units for the angle? Is it degrees, or radians, or gradients.

  2. degrees

  3. Doesn't look good to me. cot 45 deg = 1, so the answer should be somewhat less than 45 deg, but nowhere near the tiny value you show. A little ball-parking can help tell whether an answer is reasonable or not.
