#./interaufg861_en.tex#The figure shows the graph of the polynomial

$\displaystyle p(x)=x^2(a-x^2) $

as well as the tangent lines drawn at the points $ Q_i$ on the curve and thus forming a square.

Answer:

$ P$ = $ \Big($ $ \sqrt a$, $ a^2 \Big)$
$ a$ =      
$ Q_1$ = $ \Big($ , $ \Big)$
$ Q_2$ = $ \Big($ , $ \Big)$
$ A$ =      

(The results should be correct to four decimal places.)
