Yet another, defensible, possibility would be that 0^0 is 0. This is a very old issue -- and I don't mean with Mathematica. Many years ago I wrote a short note about this in the context of the APL programming language. My conclusion was that there is no really good answer, and what the value of 0^0 is should be a user-settable (global) option. Of course such an option is available in Mathematica: Unprotect[Power] Power[0,0] = 1 ivflam at gmail.com wrote: > Mathematica says 0^0 = Indeterminate > Derive says 0^0 = 1 > > May I have any opinions? > > Bruno > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
