當我使用下面的 MME 建立 PDF 時，投影片的行為很奇怪。當每條線顯示出來時，整個幻燈片都會移動，使上部部分看不見。我不確定發生了什麼事。我不認為幻燈片太擁擠，因為即使在後來的一些空得多的幻燈片上也會發生這種情況。
我在日誌中沒有收到任何警告或錯誤。
任何幫助表示讚賞。
編輯：我發現這個問題僅在我編譯幻燈片然後查看簡報時才存在。如果我從 Windows 資源管理器開啟 PDF，一切都很好。

\begin{itemize}
\item Infinite series can either diverge, converge, or be indeterminate. Many divergent series diverge very quickly, or at a constant rate.
\item Some series diverge slowly. The most famous of these is surely the harmonic series:
$ \sum_{x=1}^{\infty} \frac{1}{x} = 1 + 1/2 + 1/3 + \dots$
\item After 1000 terms, it is only about 7.85.
\item But are there series that diverge even more slowly?
\item Indeed there are!
\end{itemize}
\end{frame}
\section{Proofs of divergence}
\begin{frame}
\frametitle{The elementary proof}
\begin{itemize}
\item 1 is equal to 1
\item 1/2 is equal to 1/2
\item 1/3 + 1/4 is greater than 1/2, because $1/4 + 1/4 = 1/2 \text{ and } 1/3 > 1/4$
\item 1/5 + 1/6 + 1/7 + 1/8 is greater than 1/2, because $1/8 + 1/8 + 1/8 + 1/8 = 1/2$ and the other fractions are all greater than 1/8.
\item and so on. We just need twice as many terms in each successive sum. But we have an infinite number of terms, to that is not a problem.
\end{itemize}
