How to solve for tan 2 theta
WebJun 29, 2024 · I keep trying to solve $$\sec^2 x+ \tan^2 x = 1$$ I notice that $\tan^2 x + 1 = \sec^2 x$ so I tried substituting $\sec^2 x$ with $\tan^2 x + 1$. I get $$\tan^2 x + 1 + \tan^2 x = 1 \tag{1}$$ Then I try to solve by using the zero product property, so I subtract 1 from the right side of the equation. Leaving me with $$\tan^2 x+ \tan^2 x = 0 \tag ... WebJun 18, 2024 · tan(θ) = sin(θ) cos(θ) So, tan(θ) = 1 leads to. sin(θ) cos(θ) = 1 ⇔ sin(θ) = cos(θ) and the sine and cosine functions have the same value where θ = 45° = π 4 radians. For the same reason, tan(θ) = −1 leads to sin(θ) = …
