Prove that sin theta-2sin cube theta
Webb7 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. WebbFree math problem solver answers your trigonometry homework questions with step-by-step explanations.
