What is this syntax maxima(f, x) intended for? Just use
sage: maxima(f).powerseries(x,0) 'sum(_SAGE_VAR_x^i3,i3,0,inf) I hardly understand why it worked in previous versions. Le 24/03/2020 à 14:13, mendes a écrit :
Dear all, In previous versions of Sagemath, this worked fine: f= 1/(1-x) print( maxima(f,x).powerseries(x,0) ) Now, in Sage 9.0, this raises the error: TypeError: new_name must be a string I would be very grateful for any help.
