fonction g : vague rose…
paramètres généraux
| f | \(\left( x, y \right) \ {\mapsto} \ x^{3} + x y\) |
| grad f= | \(\left[3 \, x^{2} + y, x\right]\) |
| H= | \(\left(\begin{array}{rr} 6 \, x & 1 \\ 1 & 0 \end{array}\right)\) |
points critiques
| ( | x | = | \(0\) | ; | y | = | \(0\) | ) | \(\left(\begin{array}{rr} 0 & 1 \\ 1 & 0 \end{array}\right)\) |
