I detta avsnitt ska vi öva oss på att skilja på den linjära modellen och den exponentiella.&lt;br /&gt;
&lt;br /&gt;
  linjär: &amp;lt;math&amp;gt;y = k\cdot x + m&amp;lt;/math&amp;gt;&lt;br /&gt;
 &lt;br /&gt;
  exponentiell: &amp;lt;math&amp;gt;y = y_0\cdot a^x &amp;lt;/math&amp;gt;  där &amp;lt;math&amp;gt; y_0 &amp;lt;/math&amp;gt; är samma sak som C i tidigare exempel)&lt;br /&gt;
&lt;br /&gt;
Ibland tex inom fysiken vill man utgående från en del mätvärden hitta en modell. Om mätvärdena verkar bilda en&lt;br /&gt;
exponentiell funktion brukar man ta logaritmen av y-värdena för att linearisera grafen.&lt;br /&gt;
&lt;br /&gt;
Ofta används antingen naturliga logaritmen (&amp;#039;&amp;#039;ln&amp;#039;&amp;#039;=&amp;#039;&amp;#039;log&amp;lt;sub&amp;gt;e&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039;) med Nepers tal e=[http://apod.nasa.gov/htmltest/gifcity/e.1mil 2.718281828459045...] som bas eller&lt;br /&gt;
logaritmen (&amp;#039;&amp;#039;log&amp;#039;&amp;#039;=&amp;#039;&amp;#039;log&amp;lt;sub&amp;gt;10&amp;lt;/sub&amp;gt;&amp;#039;&amp;#039;) med 10 som bas.&lt;br /&gt;
&lt;br /&gt;
  lineariserad exponentiell: &amp;lt;math&amp;gt;log_{10}(y) = log_{10}(a) \cdot x + log_{10}(y_0)&amp;lt;/math&amp;gt;&lt;br /&gt;
 &lt;br /&gt;
  När man sedan hittat kurvan tex med lineär regression får man höja basen 10 i de funna värdena.&lt;/div&gt;</summary>
