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 ... WebFeb 5, 2024 · Explanation: First,Solve for tan(θ) By using the fact That tan(θ) = sin(θ) cos(θ) and Since You said that sin(θ) = 0.5 = 1 2 and cos(θ) = − √3 2 That means tan(θ) = sin(θ) cos(θ) = 1 2 − √3 2 = − 1 √3 = − √3 3 Lets Use the cos(θ) equation to find θ θ = cos−1( − √6 2) = ilog(u) when u = √6 + √2 2 = (√2) 1 +√3 2 Answer link Aviv S.
