In general, a series can start or end with any term. The Piecewise covers all possibilities. Look at f[x_] = Exp[-x]; Sum[SeriesCoefficient[f[x], {x, 0, n}] x^n, {n, -Infinity, Infinity}] == f[x]

| 13 hours ago | comment | added | Nasser | Are you asking what the second entry in piecewise means? It means for any other n, the result is zero. i.e. for n<0 the result is zero. True means for everything else. So in this case, everything else is n<0. To find the internal structure and levels of piecewise result, you can look at its FullForm. | |
