It works like the cross and dot product combined, and so it looks like it's not coming up with the same thing, but it's actually better than both: $v\cdot v$ gives just a scalar part (because the dot product will be non-zero and the cross product will be zero), and if you divide by that for $v^{-1} = \frac{v}{v\cdot v}$ you get a vector in the same direction as $v$ but whose magnitude is the reciprocal, so $v^{-1}\cdot v = 1$, and since we're in a land where scalars and vectors combine, this works perfectly. If you wish to add two vectors a and b, join both of them such that their tails coincide with one another. For example, we visualize the vector, However, sometimes we draw a vector with the tail away from the origin.

A unit circle has a radius of one. Direct link to jasala10's post A vector can be 3D when i. Like the dot product, it depends on the metric of Euclidean space, but unlike the dot product, it also depends on a choice of orientation or "handedness". In this case, the dot product and the cross product allow us to obtain vector division (an analog of arithmetic division). When we visualize vectors as arrows, a natural question to ask might be, "How long is it?" extrapolation methods), one often considers what is called the Samelson inverse of a vector: $$\mathbf v^{(-1)}=\frac{\bar{\mathbf v}}{\bar{\mathbf v}\cdot\mathbf v}=\frac{\bar{\mathbf v}}{\|\mathbf v\|^2}$$, (where the bar denotes complex conjugation), which can be easily shown to satisfy $\mathbf v^{(-1)}\cdot\mathbf v=\mathbf v\cdot\mathbf v^{(-1)}=1$ (the Moore-Penrose conditions in vector garb).
