I’m not.

Well, it has to do with complicated numbers. It's really difficult and boring.

If I ever feel the need to reverse a polynomial, I’ll look into it.

Well, you need to reverse the polynomial s^5 + 2*s^4 + 3*s^3 + 6*s^2 + 2*s + 1 in order to apply the Hurwitz'es Criterion to it. That's why I used it as the example in my improved Hurwitz'es Criterion implementation.

I really don’t think I need to do that.

I really don’t think I need to do that.

Sure, you can do the modified Hurwitz'es algorithm using limits, but that's way more complicated.

No, I can’t.

Why do you persist in telling me what I need to/can do?
