det(\left(\begin{matrix}3&-1&-1\\4&3&-2\\5&-2&3\end{matrix}\right))
Diagonal usulidan foydalanib matritsaning aniqlovchisini topish.
\left(\begin{matrix}3&-1&-1&3&-1\\4&3&-2&4&3\\5&-2&3&5&-2\end{matrix}\right)
Birinchi ikki ustunni to'rtinchi va beshinchi ustun sifatida qaytarish uchun asl matritsani kengaytirish.
3\times 3\times 3-\left(-2\times 5\right)-4\left(-2\right)=45
Pastki chap kiritmadan boshlab diagonal kamayish tarafga ko'paytirish ha koʻpaytmalarni qo'shish.
5\times 3\left(-1\right)-2\left(-2\right)\times 3+3\times 4\left(-1\right)=-15
Pastki chap kiritmadan boshlab diagonal ko'payish tarafga koʻpaytirish va koʻpaytmalarni qoʻshish.
45-\left(-15\right)

45 dan -15 ni ayirish.
det(\left(\begin{matrix}3&-1&-1\\4&3&-2\\5&-2&3\end{matrix}\right))
Kichik a'zolarni kengaytirish usulidan foydalanib matritsaning aniqlovchisini topish (ko'paytiruvchilarni kengaytirish deb ham nomlanadi).
3det(\left(\begin{matrix}3&-2\\-2&3\end{matrix}\right))-\left(-det(\left(\begin{matrix}4&-2\\5&3\end{matrix}\right))\right)-det(\left(\begin{matrix}4&3\\5&-2\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.
3\left(3\times 3-\left(-2\left(-2\right)\right)\right)-\left(-\left(4\times 3-5\left(-2\right)\right)\right)-\left(4\left(-2\right)-5\times 3\right)
\left(\begin{matrix}a&b\\c&d\end{matrix}\right) 2\times 2 matritsasi uchun, determinant ad-bc.
3\times 5-\left(-22\right)-\left(-23\right)
Qisqartirish.
