The small-angle approximations can be used to approximate the values of the main trigonometric functions, provided that the angle in question is small and is measured in radians: Visa mer Graphic The accuracy of the approximations can be seen below in Figure 1 and Figure 2. As the measure of the angle approaches zero, the difference between the approximation and the original … Visa mer Astronomy In astronomy, the angular size or angle subtended by the image of a distant object is often only a few arcseconds, so it is well suited to the small angle approximation. The linear size (D) is related to the angular size (X) and the … Visa mer Figure 3 shows the relative errors of the small angle approximations. The angles at which the relative error exceeds 1% are as follows: • cos θ ≈ 1 at about 0.1408 radians (8.07°) • tan θ ≈ θ at about 0.1730 radians (9.91°) Visa mer • Skinny triangle • Infinitesimal oscillations of a pendulum • Versine and haversine • Exsecant and excosecant Visa mer Webb12 juli 2024 · These formulas can be derived using x + y formulas For sin 3x sin 3x = sin (2x + x) Using sin (x + y) = sin x cos y + cos x sin y = sin 2x cos x + sin x cos 2x Using cos 2x = 1 – 2 sin 2 x and sin 2x = 2 sin x cos x = (2 sin x cos x) cos x + sin x (1 – 2sin 2 x) = 2 sin x cos 2 x + sin x – 2sin 3 x Using cos 2 x = 1 – sin 2 x
