snegSeries

◼ snegSeries[f, arg, n] expands function f into a series of order n around 0. The argument of the expansion is arg and the powers are computed using pow.

◼ The default value for n is 5.

◼ snegSeries[f[arg]] is evaluated as snegSeries[f,arg].

◼ See also: pow, superkomutator, superantikomutator.
