Find an acute angle θ when cosθ − sin θ
WebFeb 5, 2024 · If θ is an acute angle such that tan^2 θ = 8/7, then the value of [(1+sinθ)(1-sinθ)]/[1+cosθ)(1-cosθ)] is A. 7/8 B. 8/7 C. 7/4 asked May 18, 2024 in Trigonometry by … 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.
