Hello,
Does anyone know how to tell Mathematica to give the terms in a Series expansion by the order they appear and not by the specified power?
For example, the thirs term in the series
Series[(1 + x^2)^z, {x, 0, 4}]
is: 1/2 (-z + z^2) x^4
which is a fourth order power but it's the third non-zero term in the series. Can I ask Mathematica for the "third non-zero" term and have this in return? Can I ask for the n-th non zero term in a series in general?
Thanks a lot!
