Therefore, we have shown the limit of the "secant parabolas" to
be
(6) ![]()
![]()
.
Therefore, the "tangent parabola" in (5) is revealed to be the Taylor
polynomial of degree
.
Exploration 2.
The previous limits can be used to find the limit of the secant polynomials.
This is the answer we seek,
![]()
![]()
,
but Mathematica had its preferred way of writing the
answer. If you need to verify that it is correct, then
Mathematica can do it.
Of course, we could take each limit individually, then there would be no confusion.
