Hi, > why mathematica cannot give as output Sum[k[i],{i,1,m]]?! because this would be wrong! eq = Sum[f[i], {i, 1, n}] + Sum[f[i], {i, n + 1, m}] == Sum[f[i], {i, 1, m}] eq /. {n -> 5, m -> 4} gives f[1] + f[2] + f[3] + f[4] + f[5] == f[1] + f[2] + f[3] + f[4] Cheers Patrick On Fri, 2010-02-05 at 03:23 -0500, olfa wrote: > Hello mathematica community, > for Sum[k[i], {i, 1, n}] + Sum[k[i], {i, n + 1, m}] > why mathematica cannot give as output Sum[k[i],{i,1,m]]?! > please help. >
