Description 
Twovariate power series.


Synopsis 



Documentation 


In order to handle both variables equivalently
we maintain a list of coefficients for terms of the same total degree.
That is
eval [[a], [b,c], [d,e,f]] (x,y) ==
a + b*x+c*y + d*x^2+e*x*y+f*y^2
Although the sublists are always finite and thus are more like polynomials than power series,
division and square root computation are easier to implement for power series.

Series arithmetic



























Since the inner series must start with a zero,
the first term is omitted in y.
