Is there a way to force a univariate expression into the form
of a rational function (i.e., the ratio of two polynomials)?
Apart[] almost does the job, but if it's able to factor the
denominator polynomial, it does so, which leaves you with the
SUM of several rational functions. I want just a single big
rational function.
I guess this is just a special case of the problem of clearing all
sums of fractions and generating one big fraction; for example,
a/b + c/d = (ad+bc)/bd
TIA,
--Eric
