Prove that : sec^4 theta - sec^2 theta = tan^4 theta + tan^2 …
WebStart 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 then somehow it says therefore tan^2-1 = sec^2 so it replaces the entire first argument with sec^2, completely ignoring ... Web1 Use the substitution x = tanθ to show that ∫ 1 − x2 (1 + x2)2dx = ∫cos2θ dθ I'm a bit lost on how to handle this question, I have tried subtituting dθ / dx = 1 / sec2θ but I still don't reach the answer. integration trigonometry Share Cite Follow edited Mar 29, 2024 at 18:55 asked Mar 29, 2024 at 18:40 Riduan Gonzalez 179 1 8 16 Add a comment Web7 years ago. The easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into those last two equations and solve for sin θ/2 and cos θ/2. rough runner malmesbury
