Hi Folks,

I am working through a theorem involving the delta function. I have some queries in the early stages of derivation. See attached.

Thanks

1. There is k -th derivative of delta function and differencial of k-th derivative

gives k+1 derivative.

2. The k-th derivative of delta function at =0.

You may think delta function being proportional to . - Dec 9th 2010, 11:58 AMbugatti79

Yes, they are treated differently.

Please look here

Delta Function -- from Wolfram MathWorld

(17) equation.

For k-th derivative we write

and k-th degree

I am not sure you have some problems with this line

(k+1)!=(k+1)k! and (-1)(-1)^k=(-1)^(k+1)
