Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have a question about using the dirac function in a double integral.

Lets say you have the double integral over the two values x1 and x2:

int( int( sin(x1) * dirac(x1-x2) * sin(x2) ))

Does this just simplify to a single integral:

int( (sin(x1))^2 )

thanks!
