Ngā Upane e Whakamahi ana i te Ture Sarrus

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

$$det(\left(\begin{matrix}-1&0&6\\4&-3&-1\\4&6&3\end{matrix}\right))$$

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

$$\left(\begin{matrix}-1&0&6&-1&0\\4&-3&-1&4&-3\\4&6&3&4&6\end{matrix}\right)$$

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

$$-\left(-3\right)\times 3+6\times 4\times 6=153$$

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

$$4\left(-3\right)\times 6+6\left(-1\right)\left(-1\right)=-66$$

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

$$153-\left(-66\right)$$

Tango -66 mai i 153.

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).

$$det(\left(\begin{matrix}-1&0&6\\4&-3&-1\\4&6&3\end{matrix}\right))$$

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.

$$-det(\left(\begin{matrix}-3&-1\\6&3\end{matrix}\right))+6det(\left(\begin{matrix}4&-3\\4&6\end{matrix}\right))$$

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

$$-\left(-3\times 3-6\left(-1\right)\right)+6\left(4\times 6-4\left(-3\right)\right)$$

Whakarūnātia.

$$-\left(-3\right)+6\times 36$$

Tāpirihia ngā kīanga tau hei kimi i te otinga whakamutunga.
