Je kunt ook getallen laten afronden op 3 decimalen.
Typ dan SET UP=
L p
Dan kun je bij Display de
instelling veranderen in Fix=
q
en kies dan 3. Zie hiernaast
de eerste berekening.
Je kunt alleen de antwoorden laten afronden, maar er wordt
met het onafgeronde antwoord doorgerekend. Zie de derde

Normaal staat de Display-instelling op Norm2 (twee keer op
Norm=
r
drukken)
8c Een stelsel van vergelijkingen oplossen

p
Equation A
en kies Simultaneous=
q

voer je in : 1, 3 en - 4
Is de tweede vergelijking x = 10, dan voer je in: 1, 0, 10
Het antwoord staat in een tabel, maar als je er met de cursor
op gaat staan, zie je rechts onderin, als dat kan, het antwoord
als breuk.
Zo kun je ook een stelsel van 3 vergelijkingen met 3
onbekenden (dit kan t/m 6) oplossen.
Bijvoorbeeld 2x – y + 3z = 19
x + y -5z = -21
4y + 3z = 0
(hetzelfde stelsel is ook gebruikt bij matrices 4g)
8d De abc- en abcd- enz.- formule
Typ
p
Equation A
en kies Polynomial=
w
Kies nu 2=
q
voor de abc-formule of 3=
w
voor de abcd-

Zoals in de afbeelding hiernaast bovenaan staat, moet de
vergelijking op nul herleid zijn.
