Ngā Upane e Whakamahi ana i te Ture Sarrus

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

$$det(\left(\begin{matrix}4&3&-1\\5&-3&3\\-5&1&-2\end{matrix}\right))$$

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

$$\left(\begin{matrix}4&3&-1&4&3\\5&-3&3&5&-3\\-5&1&-2&-5&1\end{matrix}\right)$$

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

$$4\left(-3\right)\left(-2\right)+3\times 3\left(-5\right)-5=-26$$

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

$$-5\left(-3\right)\left(-1\right)+3\times 4-2\times 5\times 3=-33$$

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

$$-26-\left(-33\right)$$

Tango -33 mai i -26.

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).

$$det(\left(\begin{matrix}4&3&-1\\5&-3&3\\-5&1&-2\end{matrix}\right))$$

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.

$$4det(\left(\begin{matrix}-3&3\\1&-2\end{matrix}\right))-3det(\left(\begin{matrix}5&3\\-5&-2\end{matrix}\right))-det(\left(\begin{matrix}5&-3\\-5&1\end{matrix}\right))$$

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

$$4\left(-3\left(-2\right)-3\right)-3\left(5\left(-2\right)-\left(-5\times 3\right)\right)-\left(5-\left(-5\left(-3\right)\right)\right)$$

Whakarūnātia.

$$4\times 3-3\times 5-\left(-10\right)$$

Tāpirihia ngā kīanga tau hei kimi i te otinga whakamutunga.
