Greetings all,(adsbygoogle = window.adsbygoogle || []).push({});

I have a question in regards to my initial conditions. The problem as given is:

u_{t}=u_{xx}with u' = 0 at x=0 and u=0 at x=L

I was also given u={1 0<x<L/2, 0 L/2<x<L

I understand the set up of the problem and the solving of it for the most part, however I'm having trouble understanding the point that the third condition (the one about u) makes. More or less I'm stuck with trying to figure out what X is initially.

Thank you
