Ngā Upane e Whakamahi ana i te Ture Sarrus

Kimihia te tau whakatau o te poukapa mā te whakamahi i te tikanga hauroki.

$$det(\left(\begin{matrix}13&11&1\\5&17&0\\1&6&-2\end{matrix}\right))$$

Whakaroatia te poukapa taketake mā te tāruarua i ngā tīwae tuatahi e rua hei tīwae tuawhā me te tuarima.

$$\left(\begin{matrix}13&11&1&13&11\\5&17&0&5&17\\1&6&-2&1&6\end{matrix}\right)$$

Tīmata atu i te tāurunga mauī o runga, whakareatia whakararo i ngā hauroki, ka tāpiri i ngā hua ka puta.

$$13\times 17\left(-2\right)+5\times 6=-412$$

Tīmata atu i te tāurunga mauī o raro, whakareatia whakarunga i ngā hauroki, ka tāpiri i ngā hua ka puta.

$$17-2\times 5\times 11=-93$$

Tangohia te tapeke o ngā hauroki whakarunga mai i te tapeke o ngā hua hauroki whakararo.

$$-412-\left(-93\right)$$

Tango -93 mai i -412.

Ngā Upane e Whakamahi ana i te Whakaroha mā Ngā Tauriki

Kimihia te tau whakatau o te poukapa mā te whakamahi i te tikanga whakaroha ā-tauriki (te tikanga whakaroha ā-tauwehe tahi rānei).

$$det(\left(\begin{matrix}13&11&1\\5&17&0\\1&6&-2\end{matrix}\right))$$

Hei whakaroha mā ngā tauriki, me whakarea ia huānga o te haupae tuatahi ki tana tauriki, arā, ko te tau whakatau o te poukapa 2\times 2 i hangā mā te muku i te haupae me te tīwae i roto anō taua huānga, kātahi ka whakarea ki te tohu tūnga o taua huānga.

$$13det(\left(\begin{matrix}17&0\\6&-2\end{matrix}\right))-11det(\left(\begin{matrix}5&0\\1&-2\end{matrix}\right))+det(\left(\begin{matrix}5&17\\1&6\end{matrix}\right))$$

Mō te poukapa 2\times 2 \left(\begin{matrix}a&b\\c&d\end{matrix}\right), ko te tau whakatau ko ad-bc.

$$13\times 17\left(-2\right)-11\times 5\left(-2\right)+5\times 6-17$$

Whakarūnātia.

$$13\left(-34\right)-11\left(-10\right)+13$$

Tāpirihia ngā kīanga tau hei kimi i te otinga whakamutunga.
