Hi, I get with Maple: LargeSchroeder := (1 - x - sqrt(1 - 6*x + x^2))/(2*x); series(LargeSchroeder, x, 6); taylor(LargeSchroeder, x=0, 6);
1+2*x+6*x^2+22*x^3+90*x^4+394*x^5+O(x^6) 1+2*x+6*x^2+22*x^3+90*x^4+394*x^5+O(x^6) Both functions give the same result. Not so with Sage. With Sage 8.4: LargeSchroeder = SR((1 - x - sqrt(1 - 6*x + x^2))/(2*x)) print(LargeSchroeder.taylor(x, 0, 6).list()) print(LargeSchroeder.series(x, 6).list()) [1, 2, 6, 22, 90, 394, 1806] [3/2, 2, 6, 22, 90, 394] Bug or feature? Moreover taylor? .. gives hints series? .. Object `series` not found. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
