So I just finished a document I need to turn in before midnight, but I can't export to PDF for some reason. It keeps showing me this picture:

enter image description here

My guess is that I'm missing some kind of package?

The error log:

1) Lad der været givet to vektorer i planen, $\vec{a}=({3\atop 8})$
og $\vec{b}=({1\atop 6})$
\begin{enumerate}
\item Beregn $\vec{a}*\vec{b}$

\begin{enumerate}
\item $(3*1)+(8*6)=51$
\end{enumerate}
\item Beregn vinklen mellem $\vec{a}$ og $\vec{b}$

\begin{enumerate}
\item $cos(v)=\frac{51}{\sqrt{3^{2}+8^{2}}*\sqrt{1^{2}+6^{2}}}=\frac{51}{\sqrt{2701}}$
\item $cos^{-1}(\frac{51}{\sqrt{2701}})\approx11,0937$
\item $180-11,0937\approx168,906$

\item Beregn $\vec{a_{b}}$

\begin{enumerate}
\item $\vec{a_{b}}=\frac{({3\atop 8})*({4\atop 6})}{8^{2}+6^{2}}*({1\atop 6})=\frac{60}{100}*({1\atop 6})=({0,6\atop 3,6})$

2) Lad der i planen være givet punkterne $A(-2,6)$ og $B(5,1)$
\begin{enumerate}
\item Bestem en ligning (på formen $ax+by+c=0$) for linjen, som går gennem
punktet $P(1,1)$ og har $\vec{AB}$ som normalvektor.

\begin{enumerate}
\item $\vec{AB}=\vec{n}$
\item $\vec{n}=[{5-(-2)\atop 1-6}]=[{7\atop -5}]$
\item $7(x-1)-5(y-1)=0$
\item $7x-7-5y-5=0$
\item $7x-5y-12=0$
\end{enumerate}
\item Bestem en ligning (på formen $ax+by+c=0$) for linjen, som går gennem
punktet $Q(2,-3)$ og har$\vec{AB}$ som retningsvektor.

\begin{enumerate}
\item $\vec{r}=\vec{AB}=[{7\atop -5}]$
\item $\vec{n}=[{5\atop 7}]$
\item $5(x-2)+7(y-(-3))=0$
\item $5x-10+7y-(-21)=0$
\item $5x+7y+11=0$
\end{enumerate}
\item Bestem en ligning for den cirkel, som har centrum i punktet A og har
radius = $|AB|$

\begin{enumerate}
\item Centrum -2,6 og radius = $|AB|=\sqrt{74}$
\item $r=\sqrt{(5-(-2))^{2}+(1-6)^{2}}=\sqrt{74}$
\item $(x-(-2))^{2}+(y-6)^{2}\approx8,60233^{2}$
\item $(x+2)^{2}+(y-6)^{2}=74$
\end{enumerate}
\end{enumerate}
3) Lad der i planen være givet punkterne P(7,2) og Q(1,3)
\begin{enumerate}
\item Beregn vinklen mellem $\vec{PQ}$ og x-aksen

\begin{enumerate}
\item $\vec{x}=[{1\atop 0}]$
\item $\vec{PQ}=[{1-7\atop 3-2}]=[{-6\atop 1}]$
\item $cos(v)=\frac{[{-6*1\atop 1*0}]}{\sqrt{(-6)^{2}+1^{2}}*\sqrt{1^{2}+0^{2}}}=\frac{-5}{\sqrt{37}}$
\item $cos^{-1}(\frac{-5}{\sqrt{37}})\approx145,285$
\item $180-145,285=34,715$
\end{enumerate}
\item Beregn midtpunktet af linjestykket PQ

\begin{enumerate}
\item $M=(\frac{7+1}{2},\frac{2+3}{2})=(4,2.5)$
\end{enumerate}
\end{enumerate}
5) Bestem tallet t, således at vektorene $\vec{a}=({t+1\atop 4})$
og $\vec{b}=({t^{2}-2t\atop -t})$ er ortogonale.
\begin{enumerate}
\item $({t+1\atop 4})*({t^{2}-2t\atop -t})=0$
\item $t^{3}-2t+t^{2}-2t-4t=0$
\item $t^{3}-t^{2}-6t=0$
\item $t*(t^{2}-t-6)=0$
\item $t=0$
\item $t^{2}-t-6=0$
\item $1t^{2}-1t-6=0$
\item $d=(-1)^{2}-4*1*(-6)=25$
\item $t=\frac{-(-1)\pm\sqrt{25}}{2*1}=\{{3\atop -2}$
\item Løsnigen er enten 3 eller -2.
\end{enumerate}
6) Bestem centrum og radius for cirklen $x^{2}+y^{2}-16x+12y-44=0$
\begin{enumerate}
\item $(x-8)^{2}+(y+6)^{2}+44=0$
\item $(-44)+6^{2}+8^{2}=56$
\item Centrum (8,-6) og $r=\sqrt{56}\approx7,48331$\end{enumerate}

Also attached my file as a Dropbox Link in case you want to have a look at it.

Hope you guys can help me out! :)

    I don't use Lyx, but your link shows you're writing in a language with accents so the encoding for LaTeX should be T1, and the font used shouldn't be the default (Computer Modern) but Latin Modern instead (package lmodern). – Bernard Oct 7 '15 at 19:52

Under Documents > Settings > Fonts, change the LaTeX font encoding from Custom to Default:

enter image description here

There exists no 15 font encoding, hence the error 15enc.def not found. I assume you don't need any special font encoding.

  • Ah, I thought I changed the font size with that...my bad! Do you know how I make the Math font bigger though? Some of it is almost unreadable. – OmniOwl Oct 7 '15 at 19:46
  • @Vipar: Inline math is usually set to \textstyle. You might be interested in \displaystyle instead. For this you'll have to select the object in question, click on the math style select and choose "Display". – Werner Oct 7 '15 at 19:54
