    you explained that like a boss. had a lecturer confuse everyone trying to explain it in a whole lecture. Great stuff, appreciate it

    thank you sir! i have no idea why my prof couldn't just explained it the way the way you did instead of talking for 30 mins going no where, I'm subscribing to your channel

    Thank you. Two-minutes into the video, I understood how to integrate with Dirac Delta Function, but more importantly WHY it works.

    Youre the best. I have a final in 6 hours and I didn't know this would be on the test until just now.

    The definition of the Dirac Delta function states that its value is zero everywhere except for where the Dirac Delta function is centered (at zero when written as Delta(x)). So if I take any arbitrary function and multiply it by the Dirac Delta function, only the value of the arbitrary function evaluated where the Dirac Delta function is centered will survive; zero times any function is zero. However, you cannot say what Delta(x) times our sample function is without first integrating.

    I am just shocked by how easy the integrals with the dirac delta is, man I spent so much time trying to figure out how to solve these integrals and I thought it was the hardest thing ever (because they look scary) but with your examples I'm just surprised by the time I wasted, however, my bad, because I just didn't understand the definition, the definition of the dirac delta tells you exactly what to do :P

    Why does the function behave as a constant when it is multiplied by the delta dirac function? Because it will only have a value in one single point of x?
    Great video! Thanks!

    thank you so much, but in my differential equations final they've asked something like a huge function multiplied by dirac delta, with no (x) or anything so how can we do it?

    The delta function is normalised to one, so that integral should return the value of 1

  • @PeteBeast
    @PeteBeast 11 лет назад

    Great explanation! But what happens when the integral's argument isn't being multiplied by a function f(x)?
    Like, integral of (dirac(t-to))dt ?

  • @finianholland7654
    @finianholland7654 5 лет назад

    Is there anyone on the internet that can explain how to evaluate a delta function as an indefinite integral? I need it for my differential equations class but I can’t find any videos.

    please what we do if dirac has this form.....&(2t-1)

    • @TheDvnty
      @TheDvnty 6 лет назад +1

      set (2t-1)=0, solve for t. that is where delta function =1
