Kua tāruatia ki te papatopenga
\xi y=\sigma y
Tē taea kia ōrite te tāupe y ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te y.
\xi y-\sigma y=0
Tangohia te \sigma y mai i ngā taha e rua.
\left(\xi -\sigma \right)y=0
Pahekotia ngā kīanga tau katoa e whai ana i te y.
y=0
Whakawehe 0 ki te \xi -\sigma .
y\in \emptyset
Tē taea kia ōrite te tāupe y ki 0.
\xi =\frac{\sigma y}{y}
Tuhia te \frac{\sigma }{y}y hei hautanga kotahi.
\xi =\sigma
Me whakakore tahi te y i te taurunga me te tauraro.
