Het is inderdaad een goed model, maar waarom d=0, D=1 en lambda =1? Bij vraag 8 heb je geen enkele berekening gemaakt... Op basis van die berekeningen kan je pas weten welke waarde je moet invullen bij d, D en lambda..
2008-12-08 11:57:08 [Jessica Alves Pires] [reply] 
Ik ben het volledig eens met Katrijn. Je hebt Q8 niet opgelost dus hoe kom je aan de parameters? Heb je ze gewoon willekeurig gekozen?
