Description
series
should simplify its terms on a per-term basis:
sage: var('x,y') (x, y) sage: ex=1/(1-x*y-x^2) sage: ex.series(x,5) 1 + (y)*x + (y^2 + 1)*x^2 + ((y^2 + 1)*y + y)*x^3 + (((y^2 + 1)*y + y)*y + y^2 + 1)*x^4 + Order(x^5)
Compare with e.g. Pari:
? 1/(1-x*y-x^2) + O(x^5) %1 = 1 + y*x + (y^2 + 1)*x^2 + (y^3 + 2*y)*x^3 + (y^4 + 3*y^2 + 1)*x^4 + O(x^5)
