👉 Determinants are square matrices that play a crucial role in linear algebra. They are used to determine whether two vectors or matrices are linearly dependent or independent, and to calculate the determinant of a matrix. Determinants have applications in fields such as physics, engineering, economics, computer graphics, and more. Determinants can be calculated using various methods depending on the size and structure of the matrix. The most common method is to expand the matrix along its first row, then use elementary row operations to eliminate
