hi
can anyone tell me how could one go about to prove
x* (delta)' ~ -delta
where delta is the dirac delta funtion of x.
~ approximately equal
delta' = first derivative of delta
i know this can be done by using the concept of GENERALISED FUNTIONS.
WHICH INVOLVES MUTLIPLYING THE LHS OF THE EQUATION WITH A GOOD FUNCTION and taking limits to infinity to get the RHS..
I tried but there is something wrong.
can anyone help me out?
