Integrating the following delta dirac function should yield min(t,s), but how?

  1. Apr 15, 2012 #1
    1. The problem statement, all variables and given/known data
    I need to understand how to integrate
    [tex] \int_{0}^{t}\int_{0}^{s} \delta(\tau-\tau')d\tau d\tau' [/tex]
    The solution is [tex]min(t,s)[/tex]



    2. Relevant equations
    See above


    3. The attempt at a solution
    [tex]min(t,s)[/tex]

    hey Bablo

    have you tried considering each of the cases seperately (s>t,s<t)? then you can change the order of integration and integrate directly...
