Integral of dirac delta function at x=0

  1. Sep 19, 2010 #1

    Can somebody help me with this...
    Is is correct to say that, Integral(delta(0)) = 1 (limits are from -infinity to +infinity)
    I dont know latex and sorry for the inconvenience in readability.

    Examine the definition of the delta function. You will see that yes is the obvious answer.

    The [tex]\delta(x)[/tex] is not a function, so you can't evaluate it at [tex]x=0[/tex] and write [tex]\delta(0)[/tex]. Maybe you meant


    this is correct. Instead


    is meaningless, so in particular it's not 1.
