Ngā Upane e Whakamahi ana i te Ture Sarrus

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

$$det(\left(\begin{matrix}-4&-4&-4\\0&3&-2\\-2&1&-4\end{matrix}\right))$$

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

$$\left(\begin{matrix}-4&-4&-4&-4&-4\\0&3&-2&0&3\\-2&1&-4&-2&1\end{matrix}\right)$$

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

$$-4\times 3\left(-4\right)-4\left(-2\right)\left(-2\right)=32$$

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

$$-2\times 3\left(-4\right)-2\left(-4\right)=32$$

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

$$32-32$$

Tango 32 mai i 32.

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).

$$det(\left(\begin{matrix}-4&-4&-4\\0&3&-2\\-2&1&-4\end{matrix}\right))$$

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.

$$-4det(\left(\begin{matrix}3&-2\\1&-4\end{matrix}\right))-\left(-4det(\left(\begin{matrix}0&-2\\-2&-4\end{matrix}\right))\right)-4det(\left(\begin{matrix}0&3\\-2&1\end{matrix}\right))$$

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

$$-4\left(3\left(-4\right)-\left(-2\right)\right)-\left(-4\left(-\left(-2\left(-2\right)\right)\right)\right)-4\left(-\left(-2\times 3\right)\right)$$

Whakarūnātia.

$$-4\left(-10\right)-\left(-4\left(-4\right)\right)-4\times 6$$

Tāpirihia ngā kīanga tau hei kimi i te otinga whakamutunga.
