Kua tāruatia ki te papatopenga
x\cos(180-\theta )=\cos(\theta )
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\cos(180-\theta )x=\cos(\theta )
He hanga arowhānui tō te whārite.
\frac{\cos(180-\theta )x}{\cos(180-\theta )}=\frac{\cos(\theta )}{\cos(180-\theta )}
Whakawehea ngā taha e rua ki te \cos(180-\theta ).
x=\frac{\cos(\theta )}{\cos(180-\theta )}
Mā te whakawehe ki te \cos(180-\theta ) ka wetekia te whakareanga ki te \cos(180-\theta ).
