allego lo svolgimento :?: dello scritto d'esame

[EDIT] volm92 ha segnalato un errore nell'esercizio 2 nel calcolo di [tex]y_g[/tex]; il risultato di [tex][\frac{\rho^3}{3}]_0^3[/tex] è 9 e non 3; il volume quindi è il triplo di quello indicato e cioè: [tex]9 \pi \sqrt2[/tex]

Ma nel primo esercizio, punto a,perché ti basta guardare solo nella direzione di y per dire che è [tex]sup=+\infty[/tex]? Quindi basterebbe guardare se tende a infinito in una direzione qualsiasi?
Nel punto b, sempre del primo esercizio, invece quella direzione come l'hai trovata? O semplicemente hai visto "a occhio"?! :?
Il terzo punto invece me lo potresti spiegare per bene che non mi è molto chiaro quando vai a trovare i punti di minimo?! :( si,se non si fosse capito... questa pare di programma la trovo abbastanza difficile! :(

Inoltre non ho ben capito come hai fatto a calcolare la superficie laterale descritto dalla rotazione dell'archetto di circonferenza.
A me viene simile, o meglio viene il doppio di quella tua..
Allego il mio svolgimento! 8)

Grazie!

Ho risolto, ed ho capito dove sbagliavo! Scusa per il sospetto di errore, ma non riuscivo a darmi pace! Rifacendolo è tornato tutto :)

A presto!
