[solved] COLLECT bug? (10637)

(11-20-2016 11:23 AM)JMB Wrote:  The function that you're trying to collect is not a polynomial, but a rational fraction (division of two polynomials). The help for the collect command states that the argument must be a polynomial or a list of polynomials.

Of course, collect(a*b+a*c,a) / collect(a*d+a*e+d*e,a) should work as expected.

Given the above, maybe the command should error out, rather than return a value?

Perhaps Parisse will shed additional perspective on this topic.
