Exercise 77 often asks:
“Find the relative extrema of ( f(x, y, z) = x^2 + y^2 + z^2 ) subject to the constraint ( x + y + z = 1 ) and ( x^2 + y^2 = z ).”
This is a two-constraint problem requiring the extended Lagrange method and the study of bordered Hessians.
Topic: Local invertibility and Implicit Function Theorem.
Since the original text is copyrighted, I cannot reprint the exact problem. But based on common patterns in Fusco-Marcellini-Sbordone, Exercise 77 in Chapter 2 (several variables) often reads similar to:
Let f(x,y) = (x^2 y) / (x^2 + y^2) for (x,y) ≠ (0,0), and f(0,0)=0. Study continuity, partial derivatives, differentiability at (0,0).
Verify the conditions for the Implicit Function Theorem (Dini's Theorem) for the equation: $$ F(x, y) = 0 $$ Specifically, analyze the solvability with respect to $y$ (finding $y=y(x)$) or $x$ (finding $x=x(y)$), calculate the first derivative, and determine the domain of the implicit function.
(A common specific variation found in this slot is: "Studiare la risolubilità dell'equazione $y - x \sin(y) = 0$ rispetto alla variabile $y$ in prossimità dell'origine.")
Let's solve this specific variation, which is a classic Fusco-Marcellini-Sbordone example.
