Whakaoti i te secθ=25/T

$$\sec \theta = \frac { 25 } { T }$$

Whakaoti mō T

$$T=25\cos(\theta )$$

$$\nexists n_{1}\in \mathrm{Z}\text{ : }\theta =\pi n_{1}+\frac{\pi }{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe T ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te T.

$$T\sec(\theta )=25$$

He hanga arowhānui tō te whārite.

$$\sec(\theta )T=25$$

Whakawehea ngā taha e rua ki te \sec(\theta ).

$$\frac{\sec(\theta )T}{\sec(\theta )}=\frac{25}{\sec(\theta )}$$

Mā te whakawehe ki te \sec(\theta ) ka wetekia te whakareanga ki te \sec(\theta ).

$$T=\frac{25}{\sec(\theta )}$$

Whakawehe 25 ki te \sec(\theta ).

$$T=25\cos(\theta )$$

Tē taea kia ōrite te tāupe T ki 0.

$$T=25\cos(\theta )\text{, }T\neq 0$$

Whakaoti mō θ

$$\theta =-\arccos(\frac{T}{25})+2\pi n_{1}\text{, }n_{1}\in \mathrm{Z}$$

$$\theta =\arccos(\frac{T}{25})+2\pi n_{2}\text{, }n_{2}\in \mathrm{Z}\text{, }T\leq 25\text{ and }T\geq -25\text{ and }T\neq 0$$
