&lt;p&gt;&lt;b&gt;Ny side&lt;/b&gt;&lt;/p&gt;&lt;div&gt;At to vektorer er parallelle vil si at de aldri skjærer hverandre. Dette betyr videre at de to vektorene enten peker nøyaktig samme vei eller motsatt vei av hverandre. Vektorene trenger &amp;#039;&amp;#039;ikke&amp;#039;&amp;#039; å være like lange for å være parallelle.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&lt;br /&gt;
Matematisk kan dette formuleres som&lt;br /&gt;
&lt;br /&gt;
To vektorer, &amp;lt;tex&amp;gt;\vec{u}&amp;lt;/tex&amp;gt; og &amp;lt;tex&amp;gt;\vec{v}&amp;lt;/tex&amp;gt;, er &amp;#039;&amp;#039;parallelle&amp;#039;&amp;#039; dersom vi kan skrive&lt;br /&gt;
&amp;lt;tex&amp;gt;\vec{u} = k \vec{v}&amp;lt;/tex&amp;gt; hvor &amp;lt;tex&amp;gt;k&amp;lt;/tex&amp;gt; er en konstant.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
Dersom &amp;lt;tex&amp;gt;k = 1&amp;lt;/tex&amp;gt; er de to vektorene like lange og peker samme retning. Dersom &amp;lt;tex&amp;gt;k = -1&amp;lt;/tex&amp;gt; er de to vektorene like lange men peker motsatt vei.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Eksempel&amp;#039;&amp;#039;&amp;#039;&amp;lt;br&amp;gt;&lt;br /&gt;
Gitt de to vektorene &amp;lt;tex&amp;gt;\vec{u} = [5,5]&amp;lt;/tex&amp;gt; og &amp;lt;tex&amp;gt;\vec{v} = [1,1]&amp;lt;/tex&amp;gt;. Disse vektorene er parallelle siden vi kan skrive &amp;lt;tex&amp;gt;\vec{u} = 5 \vec{v}&amp;lt;/tex&amp;gt;.&lt;/div&gt;</summary>
