Kua tāruatia ki te papatopenga
\frac{\pi }{2}-0
Tuhia te 1\times \frac{\pi }{2} hei hautanga kotahi.
\frac{\pi }{2}-\frac{0\times 2}{2}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 0 ki te \frac{2}{2}.
\frac{\pi -0\times 2}{2}
Tā te mea he rite te tauraro o \frac{\pi }{2} me \frac{0\times 2}{2}, me tango rāua mā te tango i ō raua taurunga.
\frac{\pi }{2}
Mahia ngā whakarea i roto o \pi -0\times 2.
