# IntegrationResultToFunction(R, F)¶

complexExpand(i) returns the expanded complex function corresponding to i.
expand(i, x) returns the list of possible real functions of x corresponding to i.
split(u(x) + sum_{P(a)=0} Q(a, x)) returns u(x) + sum_{P1(a)=0} Q(a, x) + ... + sum_{Pn(a)=0} Q(a, x) where P1, ..., Pn are the factors of P.
