sin^2 (x) cos^2 (x) = 1 everywhere An alternate approach to proving this identity involves using the "unit circle" (radius = 1) Since the radius isSince tanθ = sinθ cosθ and secθ = 1 cosθ , ⇒ tan2θ 1 = sec2θ Hence Proved cos(x − x) = cos2x sin2x = 1 then divide by cos2x to get the result above I've assumed the one of the trigonometric results d dθ(1 tan2θ) = 2tanθsec2θ d dθsec2θ = 2secθ(tanθsecθ) = 2tanθsec2θ Thus (1 tan2θ) − sec2θ is a constantI know that and The next step would then be to say that but now what?

1+tan^2x=sec^2x proof
1+tan^2x=sec^2x proof-Dividing the numerator and denominator by $\cos x$ gives $$\frac{\sin x \cos x}{\cos x \sin x} = \frac{\tan x 1}{1 \tan x},$$ and then observe that $\tan \frac{\pi}{4} = 1$ Then recall the tangent addition identity $$\tan(\alpha \beta) = \frac{\tan \alpha \tan \beta}{1 \tan \alpha \tan \beta}$$ For what suitable choices of Using the following tan(x) = sin(x)/cos(x) cos^2(x)sin^2(x) = 1 sec(x) = 1/cos(x) for cos(x)!=0, we have 1tan^2(x) = cos^2(x)/cos^2(x) (sin(x)/cos(x))^2 =cos^2(x)/cos^2(x)sin^2(x)/cos^2(x) =(cos^2(x)sin^2(x))/cos^2(x) =1/cos^2(x) =(1

Yes, sec 2 x−1=tan 2 x is an identity sec 2 −1=tan 2 x Let us derive the equation We know the identity sin 2 (x)cos 2 (x)=1 ——(i) Dividing throughout the equation by cos 2 (x) We get sin 2 (x)/cos 2 (x) cos 2 (x)/cos 2 (x) = 1/cos 2 (x) We know that sin 2 (x)/cos 2 (x)= tan 2 (x), and cos 2 (x)/cos 2 (x) = 1 So the equation (i) after substituting becomes Ex 34, 8 Find the general solution of the equation sec2 2x = 1 – tan 2x sec2 2x = 1 – tan 2x 1 tan2 2x = 1 – tan2x tan2 2x tan2x = 1 – 1 tan2 2x tan2x = 0 tan 2x (tan2x 1) = 0 Hence We know that sec2 x = 1 tan2 x So, sec2 2x = 1 tan2 2x tan 2x = 0 taSeparate fractions Rewrite tan(x) tan ( x) in terms of sines and cosines Multiply by the reciprocal of the fraction to divide by sin(x) cos(x) sin ( x) cos ( x) Convert from cos(x) sin(x) cos ( x) sin ( x) to cot(x) cot ( x) Divide sec2(x) sec 2 ( x) by 1 1 Rewrite sec(x) sec ( x) in terms of sines and cosines
