How to eliminate the big-oh

[Franck MICHEL <Franck.Michel@vmesa12.u-3mrs.fr>]

Hi,

I've some difficulties for eliminating the big-oh in Taylor expansions.

For example, 

truncate(taylor(1/(1-t),t)) works fine (it gives the Taylor polynomial
without the remainder)

but truncate(taylor((1-x)/(1-t),t)) does not eliminate the big-oh. 

If you have any suggestion on how I could eliminate the O after a Taylor
expansion in one variable of an expression involving several variables, I
would be very interested.

Thank you
