Best ResponseYou've already chosen the best response.0cotangent is the ratio of cosine to sine for an angle. Inverse cotangent means that for a specific ratio, the output will be the angle that has that ratio. \(cot^{1}(1)\) will give us the angle for which cosine is equal to sine. This turns out to be pi/4 Add in \(cot^{1}(2)\) and \(cot^{1}(3)\) and clearly the angle won't be pi/4 anymore.

Best ResponseYou've already chosen the best response.0arccot(x) = arctan(1/x) if x>0 so arctan(1) = arccot(1) = pi/4 the rest are positive so it cant be true arccot(2) = arctan(1/2) > 0 arccot(3) = arctan(1/3) > 0
