  We often use the notation:
  \begin{talign}
    F(x) \big]_a^b = F(b) - F(a)
  \end{talign}
  \pause
  Then 
  \begin{talign}
    \int_a^b f(x)dx = F(x) \big]_a^b
  \end{talign}
  \pause\bigskip
  
  Alternative notation
  \begin{talign}
    F(x) \big|_a^b \quad=\quad \big[ F(x) \big]_a^b \quad=\quad F(x) \big]_a^b
  \end{talign}
