But what if we ask a question where the answer is some algebraic expression? The issue is that there may be many mathematically equal forms of that expression. For example, here we’re computing a derivative: And here we’re doing a factoring problem: These two answers are mathematically equal. Sometimes that’s easy to determine.

Any integral of an algebraic function can in principle be done in terms of our general DifferentialRoot objects. Turning from calculus to algebra, we’ve added the function PolynomialSumOfSquaresList that provides a kind of “certificate of positivity” for a multivariate polynomial. But if you’re doing astronomy they can really matter.
