Status: New Owner: ---- Labels: Type-Defect Priority-Medium New issue 1484 by fredrik.johansson: series should collect powers http://code.google.com/p/sympy/issues/detail?id=1484
>>> cos(1+x+x**2).series(x,0,5) x**4*sin(1)/2 - x*sin(1) - x**2*sin(1) - x**3*cos(1) - 11*x**4*cos(1)/24 - x**2*cos(1)/2 + x**3*sin(1)/6 + cos(1) + O(x**5) This is annoying. series should be clever enough to return something like cos(1) - sin(1)*x - (sin(1)+cos(1)/2)*x**2 + (sin(1)/6 - cos(1))*x**3 + (sin(1)/2 - 11*cos(1)/24)*x**4 + O(x**5) instead. Alternatively, or additionally, the printer could look out for when an Add contains an O(x**p) term and in that case print the terms in order of ascending powers of x. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
