Title: Error in HA 2 Problem 1?
Post by: Emily Deibert on October 01, 2015, 01:22:09 PM

Hi Professor,

HA2 Problem 1 a) has as the fifth problem, \begin{equation}
u_x + x^3u_x = 0
\end{equation}

Did you perhaps mean \begin{equation}
u_t + x^3u_x = 0
\end{equation}

to make an equation involving partial derivatives with respect to t AND x, like the other problems?
