Best ResponseYou've already chosen the best response.0\[\tan^2(x) +1 = \sec^2(x)\] We will sue this identity. \[\cot(x) = \tan(x)  \sec^2(x)/\tan(x) \] \[\cot(x) = [\tan^2(x) sex^2(x)]/\tan(x) \] Use the identity above \[\cot(x)= [\tan^2(x)  (\tan^2(x)  1]/\tan(x)\] \[\cot(x) =  1/\tan(x)\] 1/tan(x) is cot(x) so cot(x) = cot(x)
