                      Partial fractions

                      Reading time: 1min

                      Partial fraction expansion is used to change a rational fraction in the form , where f and g are polynomials, into an expression of the form , where gj(x) are polynomials that are factors of g(x).

                      Syntax

                      partial_fractions(Fraction)
                      
                      partial_fractions(Fraction, Ring)
                      

                      Description

                      Given a fraction of polynomials, returns a list L whose elements are lists L1, ..., Lk. The list Lj has as elements the polynomials fj(x) and gj(x).

                      Given a fraction of polynomials and a ring, returns a list L whose elements are lists L1, ..., Lk. The list Lj has as elements the polynomials fj(x) and gj(x). The decomposition is done over the specified ring.
