This gives me a value between $1$ and $-1$. $1$ means they're parallel to each other, facing same direction (aka the angle between them is $0^\circ$). $-1$ means they're parallel and facing opposite directions ($180^\circ$).For your specific question of why the dot product is 0 for perpendicular vectors, think of the dot product as the magnitude of one of the vectors times the magnitude of the part of the other vector that points in the same direction. So, the closer the two vectors' directions are, the bigger the dot product. When they are perpendicular, none of ...The dot product is a fundamental way we can combine two vectors. Intuitively, it tells us something about how much two vectors point in the same direction. Definition and …No. This is called the "cross product" or "vector product".

Definition 11.3.1 Dot Product. (a) Let u → = u 1, u 2 and v → = v 1, v 2 in ℝ 2.Note that the magnitude of the cross product is zero when the vectors are parallel or anti-parallel, and maximum when they are perpendicular. This contrasts with the dot product, which is maximum for parallel vectors and zero for perpendicular vectors. Notice that the cross product does not commute, i.e. the order of the vectors is important.Use this shortcut: Two vectors are perpendicular to each other if their dot product is 0.
