WebJan 21, 2024 · sec θ = 1 cos θ, so sec θ is (hypotenuse)/ (adjacent) = 13 5. cot θ = 1 tan θ, so sec θ is (adjacent)/ (opposite) = − 5 12. Alternatively, note that sin 2 θ + cos 2 θ = 1, so ( − 12 13) 2 + cos 2 θ = 1, and cos θ = ± 5 13. Since we're in quadrant IV, we know that cos θ is positive, so cos θ = 5 13. Then sec θ = 1 cos θ = 13 5. Web$=1\cdot \dfrac{1+\sin\theta\cdot\cos\theta}{\sin\theta\cdot\cos\theta}$ (why?) which is . $1+\sec\theta\cdot\csc\theta$ QED. Share. Cite.

WebWe must simplify (tan^2 theta - 1) <<<< note the 1 within this argument, we're taking an angle, and deducting 1 Start by simplifying the tan^2 theta angle tan^2 = sin^2+cos^2 = 1 << this we can agree on the solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still following
