$$$\frac{1}{\left|{t}\right|}\cdot \left\langle t, 0\right\rangle$$$
Din inmatning
Beräkna $$$\frac{1}{\left|{t}\right|}\cdot \left\langle t, 0\right\rangle$$$.
Lösning
Multiplicera varje koordinat i vektorn med skalären:
$$${\color{Red}\left(\frac{1}{\left|{t}\right|}\right)}\cdot \left\langle t, 0\right\rangle = \left\langle {\color{Red}\left(\frac{1}{\left|{t}\right|}\right)}\cdot \left(t\right), {\color{Red}\left(\frac{1}{\left|{t}\right|}\right)}\cdot \left(0\right)\right\rangle = \left\langle \frac{t}{\left|{t}\right|}, 0\right\rangle$$$
