Whakaoti mō S
S=\frac{D}{3}
Whakaoti mō D
D=3S
Tohaina
Kua tāruatia ki te papatopenga
3S=D
He hanga arowhānui tō te whārite.
\frac{3S}{3}=\frac{D}{3}
Whakawehea ngā taha e rua ki te 3.
S=\frac{D}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
D=3S
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4

Whakarerekētanga
\frac { d } { d x } \frac { ( 3 x ^ { 2 } - 2 ) } { ( x - 5 ) }
Whakaurunga
