Hi,
I have spent some time looking in Schaums, Eric Weisstein and google for the answer but cannot find it so I thought i'd see if anyone here could.
I would like to find the second derivative or |x| please. (wrt x).
I think there are some delta functions in there but would like to see where they come from.
Thank-you in advance.
Richard
