Chiami 8x^2 = y, e va a zero quando x tende a zero. Quindi "sistemi" il seno moltiplicando e dividendo per y.
Idem con la tangente: chiami 3x = z, e va a zero se x va a zero. Sistemi la tangente ricordandoti che è al quadrato, ovvero dividendo e moltiplicando per z^2.
Torna in x, metti insieme i due pezzi, semplifica ciò che c'è da semplificare ed il gioco è fatto!

(Comunque con gli sviluppini si fa in un attimo...)

Sì, infatti appena ho preso confidenza con gli sviluppini l'ho risolto...

Sono provvidenziali!
