Order of differentiation and integration

  1. Oct 8, 2009 #1
    I guess the following identity isn't right. Can anyone tell me what the LHS is really equal to?
    [tex]\frac{\partial}{\partial x}\int_{-\infty}^\infty\int_0^x f(s,t) dsdt = \int_{-\infty}^\infty f(x,t)dt[/tex]

    Hi toptrial! :smile:

    Looks ok to me (unless there's a convergence difficulty). :confused:

    Do you have a particular f(s,t) in mind?
