みて、No.2911からの　 emathの使い方等を参考にやってみたところ、 
No.2915の
\documentclass{jarticle}
\begin{document}
数学
\end{document}はコンパイル出来たのですが、

\begin{enumerate}[\bfseries 1.~]
  \item 次の三角関数の値を求めよ。
    \begin{edaenumerate}[(1)]
      \item $\cos \bunsuu{5}{4} \pi $
      \item $\sin \bunsuu{5}{3} \pi $
      \item $\cos \bunsuu{17}{6} \pi $
      \item $\sin \left(-\bunsuu{7}{6} \pi \right)$
      \item $\cos \left(-\bunsuu{7}{4} \pi \right)$
      \item $\tan \left(-\bunsuu{11}{6} \pi \right)$
    \end{edaenumerate}
