May 6, 2020 ... 1 Expert Answer ... sin2x = 2tanx/(1 + tan2x) = 2·2/(1 + 22) = 4/5;. cos2x = (1 - tan2x)/(1 + tan2x) = (1 - 22)/(1 + 22) = - 3/5;. tan2x = sin2x/ ... Sep 10, 2024 ... For tan2x<0, f(x)=−tan2x. Thus, f′(x)=−2sec22x when tan2x<0. The formula to find the tangent of summation of two angles is tan A + B = tan A + tan B 1 - tan A tan B Substituting A = 2 x , B = x , ⇒ tan 2 x + x tan (2x) = 2 tan (x) / (1 - tan2 (x)).
