WebJun 4, 2024 · We need. cos2θ = 1 −2sin2(θ) So, cosθ = 1 − 2sin2(θ 2) 2sin2(θ 2) = 1 − cosθ. sin2( θ 2) = 1 −cosθ 2. sin(θ 2) = ± √ 1 −cosθ 2. Answer link. WebSimplify cos (theta/3)^2-sin (theta/3)^2 cos2 ( θ 3) − sin2 ( θ 3) cos 2 ( θ 3) - sin 2 ( θ 3) Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = ( a + b) ( a - b) where a = cos(θ 3) a = cos ( …
Web$\cos^2(\theta) + \sin^2(\theta)$ is always equal to $1$ in the mathematical world. This is the Pythagorean Theorem. In the computer world, this is not so because computer arithmetic has limited precision. Moreover, even when $\theta$ is given in degrees as a fraction, $\sin^2(\theta)$ is never a fraction, except WebIf cos θ + sin θ = √2 cos θ, prove that cos θ sin θ = √2 sin θ.
