Om het aantal mogelijke permutaties en combinaties te bepalen als
u 4 mensen uit een groep van 10 selecteert
Permutaties: 10 1*( n P r ) 4 = 5040
Combinaties: 10 1/( n C r ) 4 = 210

Berekeningen van complexe getallen
(CMPLX)
Om berekeningen met complexe getallen uit te voeren drukt u eerst op
N2(CMPLX) om de CMPLX-modus in te schakelen. U kunt zowel
rechthoekige coördinaten (
a + b i ) als polaire coördinaten ( r Ƨ ) gebruiken
om complexe getallen in te voeren. Berekeningen van complexe getallen
worden weergegeven in overeenstemming met de opmaak voor complexe
getallen in het setup menu.
(2 + 6
i ) ÷ (2 i ) = 3 – i (Complexe getallenopmaak: a + b i )
( 2 + 6 W(
i ) )/( 2 W( i ) )= 3– i

Let op: • Als u een invoer en weergave van een berekeningsresultaat
wilt doen in de opmaak voor polaire coördinaten, specificeer dan de
hoekeenheid alvorens de berekening te starten. • De
Ƨ waarde van het
berekeningsresultaat wordt weergegeven in het bereik van –180° Ͻ
Ƨ Ϲ
180°.Weergave van het berekeningsresultaat als de Lineaire weergave is
geselecteerd, geeft
a en b i (of r en Ƨ ) op afzonderlijke regels weer.
