WebJan 2, 2024 · A determinant is a real number that can be very useful in mathematics because it has multiple applications, such as calculating area, volume, and other quantities. Here, we will use determinants to reveal whether a matrix is invertible by using the entries of a square matrix to determine whether there is a solution to the system of equations. Webc\cdot O=O c ⋅ O = O. Această proprietate specifică faptul că înmulțirea oricărui scalar cu o matrice zero are ca rezultat aceeași matrice zero. Din nou, această proprietate este adevărată datorită proprietății înmulțirii cu zero în sistemul de numere reale. Iată un exemplu în care c=3 c = 3 și O O este matrice zero de tip ...
