Can dot products be negative
WebJan 17, 2024 · Also, I know that the dot product between 2 vectors is negative if, denoted by $\theta$ the angle between them, it is $\frac{\pi}{2}<\theta < \frac{3\pi}{2}$. … WebApr 20, 2024 · If you already know the vectors are both normalized (of length one), then the dot product equaling one means that the vectors are pointing in the same direction (which also means they’re equal). For example, 2D vectors of (2, 0) and (0.5, 0) have a dot product of 2 * 0.5 + 0 * 0 which is 1 .
