  \begin{block}{Fundamental Theorem of Calculus}
    Suppose $f$ is a continuous function on $[a,b]$. Then
    \begin{enumerate}
    \pause
      \item If \vspace{-1ex}
        \begin{talign}
          g(x) = \int_a^x f(t)dt\,
        \end{talign} \vspace{-1ex}
        then $g'(x) = f(x)$.
    \medskip\pause
      \item Let $F$ be any antiderivative of $f$, that is, $F' = f$. Then
        \begin{talign}
          \int_a^b f(x)dx = F(b) - F(a)
        \end{talign}
    \end{enumerate}

  The first part of the theorem can be written as:\vspace{-1ex}
  \begin{talign}
    \frac{d}{dx} \int_a^x f(t)dt = f(x)
  \end{talign}
  \pause
  The second part can be written as:\vspace{-1ex}
  \begin{talign}
    \int_a^b F'(x)dx = F(b) - F(a)
  \end{talign}
