Normal form for rational fractions : ratnormal
ratnormal rewrites an expression using
it's irreductible representation. The expression is viewed
as a multivariate rational fraction with
coefficients in
(or
[i]). The variables are
generalized identifiers which are assumed to be algebraically independant.
Unlike with normal, an algebraic extension
is considered as a generalized identifier. Therefore ratnormal
is faster but might miss some simplifications if
the expression contains radicals or algebraically dependant transcendental
functions.
Input :
ratnormal((x^
3-1)/(x^
2-1))
Output :
(x^
2+x+1)/(x+1)
Input :
ratnormal((-2x^
3+3x^
2+5x-6)/(x^
2-2x+1))
Output :
(-2*x^
2+x+6)/(x-1)
