However, most commonly, the formula used in finding the angle between vectors is the dot product. Let us consider two vectors u and v and \(\theta \) be the angle between them.It also tells us how to parallel transport vectors between tangent spaces so that they can be compared. Parallel transport on a flat manifold does nothing to the components of the vectors, they simply remain the same throughout the transport process. This is why we can take any two vectors and take their dot product in $\mathbb{R}^n$.Jun 15, 2021 · The dot product of →v and →w is given by. For example, let →v = 3, 4 and →w = 1, − 2 .
