Whakaoti mō a
\left\{\begin{matrix}a=\frac{P}{\cos(5\theta )}\text{, }&\nexists n_{1}\in \mathrm{Z}\text{ : }\theta =\frac{\pi n_{1}}{5}+\frac{\pi }{10}\\a\in \mathrm{R}\text{, }&P=0\text{ and }\exists n_{1}\in \mathrm{Z}\text{ : }\theta =\frac{\pi n_{1}}{5}+\frac{\pi }{10}\end{matrix}\right.

Kua tāruatia ki te papatopenga
a\cos(5\theta )=P
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\cos(5\theta )a=P
He hanga arowhānui tō te whārite.
\frac{\cos(5\theta )a}{\cos(5\theta )}=\frac{P}{\cos(5\theta )}
Whakawehea ngā taha e rua ki te \cos(5\theta ).
a=\frac{P}{\cos(5\theta )}
Mā te whakawehe ki te \cos(5\theta ) ka wetekia te whakareanga ki te \cos(5\theta ).
