If 3 cot A = 4, check whether (1 - tan2 A) / (1 + tan2 A) = cos2 A - sin2 A or not. We know that the cot function is the reciprocal of the tan function. Sep 3, 2021 ... Tan 2A - Tan A = Tan A [2/(1-Tan^2 A) -1] = Tan A [(1 + Tan^2 A)/(1 - Tan^2 A)] = Tan A [(Cos^2 A + Sin^2 A)/(Cos^2 A - Sin^2 A)] = Tan A ... ...
