Question: Why do I get an error message when I try to use taylor command?

Hi, when I was learning to use the taylor-command I always get an error message that says: Error, (in series/abs) unable to compute series.

The exercise I was trying to solve was as easy as this:

> f:=x->sqrt(abs(x));

> plot(f(x),x=-5..5);

> taylor(f(x),x=1);

Error, (in series/abs) unable to compute series

Can someone tell me what am I doing wrong?

Many Thanks!
