Cosine of angle between vectors

WebAug 7, 2024 · The problem with the cosine is that when the angle between two vectors is small, the cosine of the angle is very close to 1 and you lose precision. An identity for this is 1 − cos ( x) = 2 sin 2 ( x / 2). If you try … More generally, direction cosine refers to the cosine of the angle between any two vectors. They are useful for forming direction cosine matrices that express one set of orthonormal basis vectors in terms of another set, or for expressing a known vector in a different basis.
