Hi Marco,
In your command taylor(f(x,y),[x,y],[0,0],2), the [0,0] option stands for the coordinates of the point you want to expand about and '2' declares the order of expansion. So your case would simply take a form like this
taylor(f(x,y),[x,y],[-1,-1],2)
Alternatively you could try '?? taylor' in command line and find a much more comprehensive help on 'taylor'.
