An \textit{inhomogeneous linear} differential equation has the form
\begin{align}
L[v ] = f,

Remember to modify the information above.
\subsubsection*{The following will give you an overview of what you can do with this template.}
\begin{Problem}
Type your problem here. \\
Personally I recommend Mathpix (https://mathpix.com/), which can easily export your ProblemBook.pdf to \LaTeX \ code.
\end{Problem}
\begin{Solution}
Write your solution here.
Example of equations. $x+1=2$. Or
$$x-1=0$$
Example of a list of equations.
\begin{align*}
x &= 1\\
y &= 2
\end{align*}
Example of a matrix.
$$\begin{pmatrix}1&0\\0&1\end{pmatrix}$$
Example of a lemma.
\begin{lemma}
This is a lemma.
\end{lemma}
Example of a proof.
\begin{proof}
Write your proof here.
\end{proof}
Example of including a picture.
\begin{center}
\includegraphics[width = 4cm]{logo-hkust.png}
\end{center}
Example of referring to a piece of code.
\lstinputlisting[language = python]{Program Solution.py}
Example of a table.
\begin{equation*}\begin{tabular}{ c c c }
& Mean & SD \\
Fall 2077 & 7.046512 & 1.714552 \\
Fall 1977 & 9.102941 & 1.568919
\end{tabular}\end{equation*}
Overall, this is a quite basic template for assignments, and above are only some basic features. I included enough packages and set a few environments. You may modify them or add features to fit your personal preference. Enjoy using it!
