Dear support the following two commands can be used to test, if a function is a polynomial or quotient of two polynomials in x variable.
sage: (x^3+x+3+1/(x))._maxima_().polynomialp([x]).sage() 0 sage: ((x^3+x+3+1)/(x^4+3))._maxima_().polynomialp([x],"constantp", "integerp").sage() 1 Is there a solution how to do this in pure Sage, without calling Maxima? (I think that each call of Maxima takes a long time on my server, especially the first call.) Many thanks.
