-0.546302

Answer 3

iwan how did you arrive at your answer

Answer 4

neither answer worked...

Answer 5

cot^-1 (-1/2) -> 1/{cot(-1/2)} -> 1/-1.83049 -> -0.546302

Answer 6

-1.107148717794090503017065460178537040070047645401432646676 radians
-63.43°

this is the same as:
\[-\tan^{-1}(2)\]
which has the same resultants.
