This is a neat example of some manual simplication tricks. I appreciate it.

I am still having problems with the new patch. See my notes on the issue
1630. I will work on extra tests for now.

Thanks for your reply. 1-2 weeks would be great. The speed sounds
excellent. Please keep us posted or let me know if you need me to test
stuff like this.

That is the big O symbol. See the docstring for order and
http://en.wikipedia.org/wiki/Big_O_notation
. It represents the remaining terms of the series.
With that being said, the reason you don't get a number is that the x
in O(x**10) gets substituted too (bug?), so it becomes 1 − 1/3 + 1/5
Hello everyone,
I have the following code:
In [1]: from sympy import *
In [2]: x=Symbol('x')
In [3]: atan(x).series(x,1,10)
Out[3]: x - x**3/3 + x**5/5 - x**7/7 + x**9/9 + O(x**10)
In [4]: atan(x).series(x,1,10).subs(x,1)
Out[4]: O(1)
what I don't understand is the Out[4] I would have expected
