Tan 2 theta - cot 2 theta
WebI've tried to solve the equation $\cot \theta = 2\cot 2\theta$ with the command 'Reduce' of Mathematica and obtained $\theta = n\pi$ as the solution with n an integer. But $\theta=n\pi$ is clearly a . ... On the other hand, if you rewrite it as $$ \tan2\theta=2\tan\theta $$ and expand, you get $$ \frac{\tan\theta}{1 … WebVerify the Identity cos (theta) (tan (theta)+cot (theta))=csc (theta) cos (θ)(tan (θ) + cot (θ)) = csc (θ) cos ( θ) ( tan ( θ) + cot ( θ)) = csc ( θ) Start on the left side. cos(θ)(tan(θ)+cot(θ)) cos ( θ) ( tan ( θ) + cot ( θ)) Simplify the expression.

Webtan²θ = sin²θ + cos²θ = 1 That is wrong. tan²θ = sin²θ/cos²θ. Secondly, the identity is tan²θ + 1 = sec²θ, not tan²θ - 1. Maybe this proof will be easier to follow: tan²θ + 1 = sin²θ/cos²θ + 1 = sin²θ/cos²θ + cos²θ/cos²θ = (sin²θ + cos²θ)/cos²θ //sin²θ + cos²θ = 1, which we substitute in. = 1/cos²θ = sec²θ Therefore, tan²θ + 1 = sec²θ.
