"Use separation of variables to find particular solutions of
[tex]u_t-u_{xx}-2u_x=0, 1<x<2, 0<t, u(1,t)=u(2,t)=0[/tex]
hint: change coordinates"
I can't find the solution. The equation seems already separated, so all I need to do is to find a change of variables, I think. But I can't find one that works.
