Re: der3??



the deriverative of a function is f'(x)
the second deriverative is the deriverative, or f''(x)
the thrid deriverative is the deriverative of the deriverative, or
f'''(x)

so, to get third order deriverative, do:  der(der(der(x)))   or...
der2(der(x))  or...   der(der2(x))  etc.
to get fourth, do der2(der2(x)) or der(der(der(der(x)))), well you get
the idea.
