Klipbordga nusxa olish

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

Diagonal usulidan foydalanib matritsaning aniqlovchisini topish.

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

Birinchi ikki ustunni to'rtinchi va beshinchi ustun sifatida qaytarish uchun asl matritsani kengaytirish.

-2\times 4\left(-2\right)-\left(-2\times 4\right)+5\times 3\times 3=69

Pastki chap kiritmadan boshlab diagonal kamayish tarafga ko'paytirish ha koʻpaytmalarni qo'shish.

4\times 4\times 5+3\left(-2\right)\left(-2\right)-2\times 3\left(-1\right)=98

Pastki chap kiritmadan boshlab diagonal ko'payish tarafga koʻpaytirish va koʻpaytmalarni qoʻshish.

69-98

Kamayib boruvchi diagonal koʻpaytmalarning yig'indisidan ko'payib boruvchi diagonal koʻpaytmalar yig'indisini ayirish.

69 dan 98 ni ayirish.

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

Kichik a'zolarni kengaytirish usulidan foydalanib matritsaning aniqlovchisini topish (ko'paytiruvchilarni kengaytirish deb ham nomlanadi).

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

Kichik a’zolarga kengaytirish uchun birinchi satrning har bir elementini o‘zining kichik a’zosiga ko‘paytiring, qaysiki ana shu elementga ega bo‘lgan satr va ustunni yo‘q qilish orqali yaratilgan 2\times 2 matritsasining maxraji hisoblanadi, so‘ngra elementning joylashuv belgisiga ko‘paytiring.

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

\left(\begin{matrix}a&b\\c&d\end{matrix}\right) 2\times 2 matritsasi uchun, determinant ad-bc.

-2\left(-2\right)-\left(-2\right)+5\left(-7\right)

Qisqartirish.
