Ngā Upane Otinga

Tīkina te uara \sin(90) mai i te ripanga uara pākoki.

$$5\times 1+2\cos(0)-2\sin(270)+10\cos(180)$$

Whakareatia te 5 ki te 1, ka 5.

$$5+2\cos(0)-2\sin(270)+10\cos(180)$$

Tīkina te uara \cos(0) mai i te ripanga uara pākoki.

$$5+2\times 1-2\sin(270)+10\cos(180)$$

Whakareatia te 2 ki te 1, ka 2.

$$5+2-2\sin(270)+10\cos(180)$$

Tāpirihia te 5 ki te 2, ka 7.

$$7-2\sin(270)+10\cos(180)$$

Tīkina te uara \sin(270) mai i te ripanga uara pākoki.

$$7-2\left(-1\right)+10\cos(180)$$

Whakareatia te 2 ki te -1, ka -2.

$$7-\left(-2\right)+10\cos(180)$$

Ko te tauaro o -2 ko 2.

$$7+2+10\cos(180)$$

Tāpirihia te 7 ki te 2, ka 9.

$$9+10\cos(180)$$

Tīkina te uara \cos(180) mai i te ripanga uara pākoki.

$$9+10\left(-1\right)$$

Whakareatia te 10 ki te -1, ka -10.

$$9-10$$

Tangohia te 10 i te 9, ka -1.
