Homework Statement
Hi there, I'm stuck at a problem where I have (sorry i don't know how to use mathtype so I'll try my best at making this clear) the integral of a dirac delta function squared:
int[delta(x*-x)^2] between minus infinity and infinity (x*=constant)
I know that the function equals x*(int[delta(x)^2]) but I'm at a bit of a loss as to why :/
The Attempt at a Solution
I'm pretty sure the function int[delta(x-x*)f(x)dx]=f(x*) has something to do with it but I can't quite figure it out.
If f(x)=delta(x-x*) then f(x*)=delta(x*-x*) :? can f(x) even be another delta function?
Thanks for any replies,
JSG
