For example, Table[D[Product[f[k,z],{k,0,m}],{z,n}],{m,0,2},{n,0,2}] Bob Hanlon ---- Esa A E Peuha <esa.peuha at helsinki.fi> wrote: > Mathematica 5.0 seems to have trouble with parsing this input: > > In[1]:= D[Product[f[k,z],{k,0,m}],{z,n}] > > Out[1]= D[Product[f[k, z], {k, 0, m}], z] > > Has this been fixed in newer versions? > > -- > Esa Peuha > student of mathematics at the University of Helsinki > http://www.helsinki.fi/~peuha/ >
