WebMay 13, 2024 · 1 Answer. Dean R. May 13, 2024. tanθ = 3 4 means an opposite of 3, an adjacent of 4, so a hypotenuse of 5, because 32 +42 = 52. cosθ = adjacent hypotenuse = … 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.
