    Clarification of PDE.

    What is the meaning of \;\;\frac{\partial u}{\partial t}(x,0)

    Is it equal to \;\;\frac{\partial u(x,t)}{\partial t}\;\;then\;set\;x=0

    or \;\;\;\frac{\partial u(x,0)}{\partial t}

    It means the first. You can't calculate

    \;\;\;\frac{\partial}{\partial t}\left( u(x,0) \right).
