Whakaoti mō δ
\delta =\frac{30}{R\left(R-1\right)}
R\neq 1\text{ and }R\neq 0
Whakaoti mō R (complex solution)
R=\frac{\sqrt{\delta \left(\delta +120\right)}+\delta }{2\delta }
R=\frac{-\sqrt{\delta \left(\delta +120\right)}+\delta }{2\delta }\text{, }\delta \neq 0
Whakaoti mō R
R=\frac{\sqrt{\delta \left(\delta +120\right)}+\delta }{2\delta }
R=\frac{-\sqrt{\delta \left(\delta +120\right)}+\delta }{2\delta }\text{, }\delta >0\text{ or }\delta \leq -120
Tohaina
Kua tāruatia ki te papatopenga
\delta R^{2}-\delta R=30
Whakamahia te āhuatanga tohatoha hei whakarea te \delta R ki te R-1.
\left(R^{2}-R\right)\delta =30
Pahekotia ngā kīanga tau katoa e whai ana i te \delta .
\frac{\left(R^{2}-R\right)\delta }{R^{2}-R}=\frac{30}{R^{2}-R}
Whakawehea ngā taha e rua ki te R^{2}-R.
\delta =\frac{30}{R^{2}-R}
Mā te whakawehe ki te R^{2}-R ka wetekia te whakareanga ki te R^{2}-R.
\delta =\frac{30}{R\left(R-1\right)}
Whakawehe 30 ki te R^{2}-R.
