Ngā Upane e Whakamahi ana i te Ture Sarrus

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

$$det(\left(\begin{matrix}-4&0&-1\\9&4&-1\\13&5&0\end{matrix}\right))$$

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

$$\left(\begin{matrix}-4&0&-1&-4&0\\9&4&-1&9&4\\13&5&0&13&5\end{matrix}\right)$$

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

$$-9\times 5=-45$$

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

$$13\times 4\left(-1\right)+5\left(-1\right)\left(-4\right)=-32$$

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

$$-45-\left(-32\right)$$

Tango -32 mai i -45.

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).

$$det(\left(\begin{matrix}-4&0&-1\\9&4&-1\\13&5&0\end{matrix}\right))$$

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.

$$-4det(\left(\begin{matrix}4&-1\\5&0\end{matrix}\right))-det(\left(\begin{matrix}9&4\\13&5\end{matrix}\right))$$

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

$$-4\left(-5\left(-1\right)\right)-\left(9\times 5-13\times 4\right)$$

Whakarūnātia.

$$-4\times 5-\left(-7\right)$$

Tāpirihia ngā kīanga tau hei kimi i te otinga whakamutunga.
