Whakaoti mō R
R=\frac{1}{2}=0.5
Tohaina
Kua tāruatia ki te papatopenga
1=2R
Tē taea kia ōrite te tāupe R ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te R.
2R=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
R=\frac{1}{2}
Whakawehea ngā taha e rua ki te 2.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
