Whakareatia te taurunga me te tauraro ki te haumi hiato o te tauraro, 1+i.
\frac{\left(1+i\right)\left(1+i\right)}{1^{2}-i^{2}}
Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
\frac{\left(1+i\right)\left(1+i\right)}{2}
Hei tōna tikanga, ko te i^{2} ko -1. Tātaitia te tauraro.
\frac{1\times 1+i+i+i^{2}}{2}
Me whakarea ngā tau matatini 1+i me 1+i pēnā i te whakarea huarua.
\frac{1\times 1+i+i-1}{2}
Hei tōna tikanga, ko te i^{2} ko -1.
\frac{1+i+i-1}{2}
Mahia ngā whakarea i roto o 1\times 1+i+i-1.
\frac{1-1+\left(1+1\right)i}{2}
Whakakotahitia ngā wāhi tūturu me ngā wāhi pōhewa ki 1+i+i-1.
\frac{2i}{2}
Mahia ngā tāpiri i roto o 1-1+\left(1+1\right)i.
i
Whakawehea te 2i ki te 2, kia riro ko i.
Re(\frac{\left(1+i\right)\left(1+i\right)}{\left(1-i\right)\left(1+i\right)})
Me whakarea te taurunga me te tauraro o \frac{1+i}{1-i} ki te haumi hiato o te tauraro, 1+i.
Re(\frac{\left(1+i\right)\left(1+i\right)}{1^{2}-i^{2}})
Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
Re(\frac{\left(1+i\right)\left(1+i\right)}{2})
Hei tōna tikanga, ko te i^{2} ko -1. Tātaitia te tauraro.
Re(\frac{1\times 1+i+i+i^{2}}{2})
Me whakarea ngā tau matatini 1+i me 1+i pēnā i te whakarea huarua.
Re(\frac{1\times 1+i+i-1}{2})
Hei tōna tikanga, ko te i^{2} ko -1.
Re(\frac{1+i+i-1}{2})
Mahia ngā whakarea i roto o 1\times 1+i+i-1.
Re(\frac{1-1+\left(1+1\right)i}{2})
Whakakotahitia ngā wāhi tūturu me ngā wāhi pōhewa ki 1+i+i-1.
Re(\frac{2i}{2})
Mahia ngā tāpiri i roto o 1-1+\left(1+1\right)i.
