In the senior secondary years, when students extend their study to polynomial functions, they come across the rational root
theorem (see www.wikipedia.org).
If P is of odd degree, it has a rational root
He also proved that the dynatomic curve [[PHI].sub.4,[sigma]](x) = 0 with [sigma](x) = [x.sup.2] + a has no rational points, i.e., [[PHI].sub.4,[sigma]](x) has no rational roots
for rational values of a .
Yet, her struggle continued, for she was constantly targeted for reasons which had no rational roots
If we collocate (24) at the (N) Legendre rational roots
of [R.sub.N + 1](t), then we get
He accepted only positive rational roots
and ignored all others.
Current research in decision-making has taken a departure from its purely rational roots
(Dawes, 1988; Kahneman, Slovic & Tversky, 1982).
Although a lot of people want to pretend that conflict has purely rational roots
, the emotional energy tapped by conflict can only be explained by multiple origins.
