WebJul 29, 2016 · If there are no arguments in Poly other than the expression, then all symbols (and many other subexpressions) will become generators. If only x is given, then everything else becomes 'buried' in the coefficient ring. The word 'elevate' was intended describe the move from the set of coefficients to the set of generators. I'm sorry if that was misleading :) Webdef coeff (f, x, n = 1, right = False): # the semantics of coeff_monomial and Expr.coeff are different; # if someone is working with a Poly, they should be aware of the # differences and chose the method best suited for the query. # Alternatively, a pure-polys method could be written here but # at this time the ``right`` keyword would be ignored because Poly # …
