Webbsmall angle approximation is used usually to replace non linear trigonometric function by some simpler and more importantly linear equivalent functions. For example if angle is small enough: - sin (x) is … Webb13 apr. 2024 · However, the rotation rates of the swimmers are in general different and read, Ω 1 = v (sin χ 1, 0, cos χ 1) / a for swimmer one and Ω 2 = v (sin χ 2, 0, cos χ 2) / a for swimmer two. Chemical and hydrodynamic perturbations in the velocity and rotation rate of the swimmers change the corresponding torsion and curvature of the swimmers' helical …
WebbThis is why some of us really like math!) So for many applications in physics — where we can keep the angles less than about 20 o, we can use the small angle approximations: … WebbSpecific uses 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 …
