+\begin{frame}[t,fragile]
+ \frametitle{PI}
+ \framesubtitle{}
+
+ \begin{itemize}
+ \item The goal of this exercise is to compute an approximate value of $\pi$
+ \item To compute $\pi$, we will use two identities:
+ \begin{equation}
+ \label{eq:1}
+ \arctan(1) = \frac{\pi}{4}
+ \end{equation}
+ \begin{equation}
+ \label{eq:2}
+ \int_{0}^{x} \frac{1}{1+y^{2}} {\rm d}y = arctan(x)
+ \end{equation}
+ Then, it follows that
+ \begin{equation}
+ \label{eq:4}
+ \pi = 4 \int_{0}^{1} \frac{1}{1+x^{2}} {\rm d}x
+ \end{equation}
+ \item Using a Riemann sum, we can approximate the integral in Eq.\,\eqref{eq:2}
+ \begin{equation}
+ \label{eq:3}
+ \pi \approx \frac{4}{n}\sum_{i=0}^{n}\frac{1}{1+(i/n)^{2}}
+ \end{equation}
+ \end{itemize}
+\end{frame}
+
+\begin{frame}[t,fragile]
+ \frametitle{Poisson}
+ \framesubtitle{}
+
+ \begin{itemize}
+ \item Let us consider the following Poisson problem
+ \begin{equation}
+ \label{eq:5}
+ \left\{ \begin{array}{rcl}
+ \Delta u = f(x, y) & \text{in} & \Omega, \\
+ u(x, y) = 0 & \text{on} & \partial\Omega.
+ \end{array}\right.
+ \end{equation}
+ \end{itemize}
+\end{frame}
+
+\begin{frame}[t,fragile]
+ \frametitle{Poisson}
+ \framesubtitle{}
+
+ \begin{itemize}
+ \item The 2D domain is uniformly discretized using $N+1$ points in each
+ direction:
+ \begin{equation}
+ \label{eq:6}
+ \left\{ \begin{array}{l}
+ (x_{i}, y_{j}), \\
+ \{x_{i}\}, i = 1, ..., N+1, \\
+ \{j_{i}\}, i = 1, ..., N+1.
+ \end{array}\right.
+ \end{equation}
+ The grid spacings are
+ $\Delta x = \Delta y = 1 / N$ (we assume domains of length one).
+ \item The Laplacian is approximated using second-order centered
+ finite-differences:
+ \begin{align*}
+ \Delta u(x, y) &= \frac{\partial^{2} u}{\partial x^{2}} + \frac{\partial^{2} u}{\partial y^{2}} \approx \frac{u_{i+1, j}- 2u_{i,j} + u_{i-1, j}}{\Delta x^{2}} + \frac{u_{i, j+1}- 2u_{i,j} + u_{i, j-1}}{\Delta y^{2}}\\
+ &= \frac{u_{i+1, j} + u_{i-1, j} + u_{i, j+1} + u_{i, j-1} - 4u_{i, j}}{\Delta x^{2}}
+ \end{align*}
+ \end{itemize}
+\end{frame}
+
+\begin{frame}[t, fragile]
+ \frametitle{Poisson}
+ \framesubtitle{}
+
+ \begin{itemize}
+ \item This defines a 4-point stencil
+ \end{itemize}
+ \vspace{4cm}
+ \begin{itemize}
+ \item The system of linear equations is solved using the Jacobi method
+ \item Iterations are done until the error is lower than a prescribed tolerance
+ \end{itemize}

+
+ \begin{itemize}
+ \item Let solve the Poisson problem with
+ \begin{equation}
+ u(x, y) = 0\label{eq:8}
+ \end{equation}
+ on the boundaries and
+ \begin{equation}
+ f = -200\pi^{2}\sin(10\pi x)\sin(10\pi y)\label{eq:7}
