Misterx76

Grazie a tutti per le risposte. Dopo un periodo in cui non ho potuto dedicarmi a queste questioni, oggi finalmente riesco ad occuparmene nuovamente. Fino ad ora ho sempre usato LaTeX con la catena DVI->ps->PDF ed avrei continuato così se non avessi avuto il problema con il pacchetto underscore. Come suggerito da OldClaudio, ho letto la guida di PdfTricks ed ora, usando PdfLaTeX (con TeXStudio e TexLive2025) mi compila il codice senza errori, ma non mi visualizza il disegno.
Credo di dover fare ancora qualcosa (OldClaudio mi ha suggerito di dare da terminale/finestra comandi il comando texdoc pdftriks) e nella guida si parla di Shell escape, ma in entrambi i casi non ho capito e non so cosa fare. Vi chiederei qualche delucidazione in merito.
Vi ringrazio ancora per la disponibilità.
Allego il codice nella sua ultima versione.

La scritta xB0 compare al posto del simbolo ° in ogni posto in cui è stato digitato.

Per quanto riguarda l’uso di un programma rispetto ad un altro è direi una scelta di abitudine; ognuno può preferirne uno che qualcun altro non ritiene adeguato.

Grazie.

Si in effetti sono stato ermetico.
Non riesco a centrare verticalmente nella prima colonna della tabella la quantità $\Delta<0$, senza aggiungere \vspace{-0.225cm}, misura determinata per tentativi.
Volevo sapere se esisteva un metodo valido, senza procedere per tentativi.
Grazie

Per quanto riguarda la terza colonna, “Risultato” è matematicamente, logicamente e didatticamente sbagliato. La locuzione “per ogni x in R” è quanto di peggio si possa immaginare.

Sebbene non sia particolarmente esperto di LaTeX, da tecnico della Matematica, mi potresti spiegare meglio cosa intendessi tu con le precedenti “critiche”?

E’ perfetto!
Grazie mille!!!

Ho provato con i tuoi suggerimenti.

Ottengo il riempimento, sebbene non abbia capito come fare in modo che il simbolo utilizzato non esca dai bordi del rettangolo usato e che lo riempia proprio tutto.

Non sono, invece, riuscito a sostituire al simbolo matematico un punto di pstricks (comando \psdot[]) .
Mi potresti aiutare?
Grazie

In stampa compare il tratteggio. A questo punto userò il pacchetto mnsymbol che non mi da problemi sebbene non mi piaccia troppo come rende il comando \wideparen.
Grazie
