newtype CommutativeRing r => UPoly r x Source

Polynomials over a commutative ring, indexed by a phantom type x that denote the name of the variable that the polynomial is over. For example UPoly Q X_ is Q[x] and UPoly Q T_ is Q[t].

deg :: CommutativeRing r => UPoly r x -> IntegerSource

The degree of the polynomial.

toUPoly :: (CommutativeRing r, Eq r) => [r] -> UPoly r xSource

Take a list and construct a polynomial by removing all zeroes in the end.

monomial :: CommutativeRing r => r -> Integer -> UPoly r xSource

Take an element of the ring and the degree of the desired monomial, for example: monomial 3 7 = 3x^7

lt :: CommutativeRing r => UPoly r x -> rSource

Compute the leading term of a polynomial.

deriv :: CommutativeRing r => UPoly r x -> UPoly r xSource

Formal derivative of polynomials in k[x].
