#./interaufg861_en.tex#The figure shows the graph of the polynomial
as well as the tangent lines drawn at the points
on the curve and thus forming a square.
Find the extremum
of the polynomial in terms of the parameter
and sketch the graph of the derivative
for
.
For which
do the tangent lines, whose slope is
touch the polynomial
at exactly
points
What is the area
of the square enclosed by these tangents?
Answer:
=
,
=
=
,
=
,
=
(The results should be correct to four decimal places.)
