'시험' 수업의 대체 솔루션 번호 매기기

저는 현재 작년 시험의 답안을 작성하고 있는데, 필요한 경우 동일한 문제에 대한 답안의 번호를 매길 수 있는 방법이 없다는 것을 알게 되었습니다. (어떤 질문은 수많은 해결책으로 끝납니다.)

\begin{questions}
\question Suppose $\cos 2\theta=k$, express $\sin^6 \theta-\cos^6 \theta$ in terms of $k$.
\printanswers
\begin{solution}
Notice that 
\begin{align*}
k & =\cos 2\theta\\
& =2\cos^2 \theta-1\\
& =1-2\sin^2 \theta
\end{align*}
Hence, both $\sin^2 \theta$ and $\cos^2 \theta$ can be expressed in terms of $k$ as follow:\\
\begin{equation}
\label{eq:eq1}
    \sin^2 \theta=\dfrac{1-k}{2} \quad \text{and} \quad
\cos^2 \theta=\dfrac{k+1}{2}\\
\end{equation}
Substituting Equation \eqref{eq:eq1} yields
\begin{align*}
    \sin^6 \theta-\cos^6 \theta &= \left(\dfrac{1-k}{3}\right)^3-\left(\dfrac{k+1}{3}\right)^3\\
    &=-\dfrac{k^3+3k}{4}
\end{align*}

번호 매기기를 하고 싶습니다."해결 방법 2:", 가능하다면, 그리고 질문에 해결책이 하나만 있다면, 보고 싶습니다. "해결책:" 대신. 어떻게 할 수 있니?

답변1

쉬운 방법은 솔루션 환경 내에 열거 환경을 추가하는 것입니다.
