RootSum
RootSum[f, form]
represents the sum of 
for all x that satisfy the polynomial equation 
.
Details
- f must be a Function object such as
. - form need not correspond to a polynomial function.
- Normal[expr] expands RootSum objects into explicit sums involving Root objects.
- f and form can contain symbolic parameters.
- RootSum[f, form] is automatically simplified whenever form is a rational function.
- RootSum is often generated in computing integrals of rational functions.
