Convection Equation

\begin{displaymath}
{\partial u \over \partial t} + a {\partial u \over \partial x} = f(x,t)\end{displaymath}

\begin{displaymath}
t^n \equiv t^0 + n\Delta t\quad x_j \equiv x_0 + j\Delta x\quad
u^n_j \equiv u(x_j,t^n) \quad
f^n_j \equiv f(x_j,t^n)\end{displaymath}

\begin{displaymath}
C \equiv {a \Delta t\over \Delta x}\end{displaymath}
