Reasoning purely by symmetry, doesn't it seem that where you are headed here is toward an extended rational polynomial class that handles rational polynomials of a base variable and simple functions of a base variable (such as trig functions, log and exp)? If so, then having some kind of unified c

Hi, I used already the classes of the analysis package: http://commons.apache.org/math/userguide/analysis.html There is already a fine class for Polynomial Functions which can calculate the derivation: PolynomialFunction.derivative() I would like to suggest a class called "RationalFunction" wh
