Terms in this set (12) sin^2xcos^2x= 1⇒ 1 tan 2 2x tan 2x = 1 ⇒ tan 2x (1tan 2x) = 0 So, tan 2x = 0 or tan 2x = 1 = tan (3π/4) Formula used tan θ = 0 ⇒ θ = nπ , n ∈ l and tan θ = tan α ⇒ θ = kπ ± α, k ∈ l By using above formula, we have 2x = nπ or 2x = kπ ± 3π/4 ⇒ x = nπ/2 or x = kπ/2 ± 3π/8 Please see below (1tan^2x)/(1tan^2x) = (1sin^2x/cos^2x)/(1sin^2x/cos^2x) = ((cos^2xsin^2x)/cos^2x)/((cos^2xsin^2x)/cos^2x) = (cos^2xsin^2x)/(cos^2xsin^2x) =
