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) =

Sec^4x sec^2x = tan^4x tan^ 2x Taking LHS We know that the identity, (1 tan^2x)= sec^2x => ( 1 tan^ 2x) ^ 2 ( 1 tan^ 2x) => 1 tan^ 4x 2tan^ 2x 1 tan^ 2x => tan^ 4x tan^ 2x = > RHS Hence, LHS = RHS One answer is to say that, properly, the identity is $\sec^2x=1\tan^2x$, where the sides fail to be defined at the same values Share Improve this answer Follow edited Nov 27A follow up proof to accompany sin^2 cos^2 =1 Another identity that is used quite a bit, especially in calculus involving trigonometric functionsSolution for Prove Cos2x=1tan^2x/1tan^2x Want to see this answer and more?

We may use any one of the below mentioned four as formula of cos2x as per our requirement ** cos2x= cos^2x sin^2x ** cos2x= 2cos^2x–1 ** cos2x = 1–2sin^2x ** cos2x = (1tan^2x)/(1tan^2x)If you let u=tanx in integral (tan^2)x you getIntegral of tan^2 (x) \square!
