Question: series - higher order

I always found it odd that the end of a series was truncated with O(x^9) or whatever.

convert ( a, polynom) gets rid of it, but it just stops.  Could the O(x^9) be replaced with a +... or even a -... ?

series(tan^(-1)(x),x,9)
                              

convert(%,polynom)
                               

 

What's the best way to add a + ... to the end of that.
