$$$\frac{1}{\left|{t}\right|}\cdot \left\langle t, 0\right\rangle$$$

Laske $$$\frac{1}{\left|{t}\right|}\cdot \left\langle t, 0\right\rangle$$$.

Kerro vektorin jokainen koordinaatti skalaarilla:

$$${\color{Magenta}\left(\frac{1}{\left|{t}\right|}\right)}\cdot \left\langle t, 0\right\rangle = \left\langle {\color{Magenta}\left(\frac{1}{\left|{t}\right|}\right)}\cdot \left(t\right), {\color{Magenta}\left(\frac{1}{\left|{t}\right|}\right)}\cdot \left(0\right)\right\rangle = \left\langle \frac{t}{\left|{t}\right|}, 0\right\rangle$$$
