Again, this is not what I get in the current master branch:
In [1]: (sin(x)/x**10).series(x,0,10)
Out[1]:
3 5
1 1 1 1 1 x x x
── - ──── + ────── - ─────── + ──────── - ──────── + ────────── - ────────────
9 7 5 3 362880⋅x 39916800 6227020800 130767436800
x 6⋅x 120⋅x 5040⋅x
7 9
x x ⎛ 10⎞
─ + ─────────────── - ────────────────── + O⎝x ⎠
0 355687428096000 121645100408832000
It works as expected. Can you check which version of sympy you are
actually using? Is it the master branch or a released version?
