Wiskunde schoolexamenstof H1 t/m H4
H1 ‘Formules en grafieken’
Formule opstellen:
y = ax + b
1) a = Δy/Δx
2) punt invullen, hieruit volgt b
3) formule noteren

belangrijk!
- zelfde r.c dan is a hetzelfde
- lijnen evenwijdig is a hetzelfde

Lijn tekenen manieren:
1) snijpunt met de y-as en r.c
2) tabel maken van 2 punten

Kwadratisch verband:

🙂
formule: y = ax² + bx + c

🙁
a > dalparabool ( )
a < bergparabool ( )
nulpunt berekenen > fcn, nulpunt
top berekenen > fcn, extreme waarden
snijpunt berekenen > fcn, snijpunt

Kwadratische formule opstellen:
situatie formule

formule met top (p , q) y = a(x - p)² + q
voorbeeld:
top (3,5), punt (-1,3)
y = a(x - 3)² - 5
a(-1 -3)² - 5 = 3
16a - 5 = 3
16a = 8
a = 0,5




Notities:
1) zorg altijd dat de letters kloppen in de formule!!

, H2 ‘Veranderingen’




Toenamediagram maken:
1) tabel maken
x-interval bij Δx = … Δy
2) diagram maken
voorbeeld




Δy/Δx:
- gemiddelde verandering
- differentiequotiënt
- gemiddelde snelheid
- richtingscoëfficiënt
- helling

Snelheid op één moment:
Bij een tijd-afstand grafiek neem je de snelheid op het tijdstip t = a met het differentie
coëfficiënt op het interval [a,a + Δt]. Je neemt bijvoorbeeld Δt = 0,001
