Primer cal que determinis els punts d'intersecció de les funcions f(x) i g(x). Un cop trobats, les abscisses d'aquests punts són els extrems de la integral definida.
No, case is unimportant
Yes, case must match

Atenció, l'àrea no pot ser negativa. Cal fixar-se si f(x) > g(x) en l'interval a integrar o si f(x) < g(x).
