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 tan 2 (x) 1= 1/cos 2 (x) ——–(ii) How do you verify the equation is an identity?Question I need to prove the identity (1tan^2x)cot^2x=csc^2x Found 2 solutions by Alan3354, Regrnoth Answer by Alan3354() (Show Source) You can put this solution on YOUR website!

Proving the trigonometric identity $(\tan{^2x}1)(\cos{^2(x)}1)=\tan{^2x}$ has been quite the challenge I have so far attempted using simply the basic trigonometric identities based on the Pythagorean Theorem I am unsure if these basic identities are unsuitable for the situation or if I am not looking at the right angle to tackle this problemHyperbolic Definitions sinh(x) = ( e x ex)/2 csch(x) = 1/sinh(x) = 2/( e x ex) cosh(x) = ( e x ex)/2 sech(x) = 1/cosh(x) = 2/( e x ex) tanh(x

Sin (θ), Tan (θ), and 1 are the heights to the line starting from the x axis, while Cos (θ), 1, and Cot (θ) are lengths along the x axis starting from the origin The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functionsPythagorean identities are identities in trigonometry that are extensions of the Pythagorean theorem The fundamental identity states that for any angle θ, \theta, θ, cos 2 θ sin 2 θ = 1 \cos^2\theta\sin^2\theta=1 cos2 θsin2 θ = 1 Pythagorean identities are useful in simplifying trigonometric expressions, especially in(1/sin 2 x) 2 = (1/tan 2 x) 2y Identity used cosec 2 x cot 2 x = 1 Explanation (1/sin 2 x) 2 = (1/tan 2 x) 2y ⇒ cosec 2 x 2 = cot 2 x 2y ⇒ cosec 2 x cot 2 x 2 = 2y ⇒ 1 2 = 2y ∴ The value of y is 3/2
