  \section{Fundamental Theorem\\of Calculus}
  If \(f\) is continuous on the closed interval \([a,b]\) and \(F\) is the indefinite integral of \(f\) on \([a,b]\), then
  \begin{equation}
    \int_a^b f(x)\,\mathrm{d}x = F(b)-F(a).
  \end{equation}

  \section{Conclusion}
  This is a great poster format!
