Small Angle Approx - Everyone knows the picture that explains instantly the small angle approximation to the sine function (as defined by the parametrisation of the unit circle): What's the length of that arc?. Learn how to use sine, cosine and tangent approximations for small angles in radians. See examples, values, taylor series and uses in astronomy, engineering and optics. The angular sizes of. The small angle approximation is a trick that we can use to make it easier to work with trigonometric functions when looking at small angles. The three small angle approximations.
