Problema limite

Inviato: giovedì 6 dicembre 2007, 22:49

Il limite in questione è un limite di difficoltà 2 (stelline) :(

è da risolvere con i limiti notevoli o almeno questo è scritto

fatto con altri metodi mi è riuscito ma in questione volevo cercare di seguire la difficoltà

lim con x tendente a 0

la funzione è :

[(e^2x)+cos3x+(1+x)^(1/2)-3 ] / (arctanx+arcsinx)

grazie

[(e^2x)-1]+[cos3x-1]+[(1+x)^(1/2)-1 ]

poi dividi e moltiplichi per x e son tutti limiti notevoli (o quasi).

più che altro avevo trovato qualche problema con il cos3x, però in effetti mi ero un pò perso in un bicchiere d'acqua,oggi prima di vedere che il forum era aperto lo ho risolto.

il fatto è che mi sono studiato limite notevole spezzettando l'intero limite in tanti piccoli limiti.

è legale?

Sì, se poi fai i limiti tutti insieme alla fine e non metà per volta.
