Symmetric Matrix & Skew Symmetric Matrix (Definition & Properties)

mathswithmuza on Instagram: "Determinants are a fundamental concept in linear algebra that provide a single numerical value associated with a square matrix. They encode important properties of the matrix, such as whether it is invertible or singular. For example, if the determinant of a matrix is zero, the matrix does not have an inverse, and its rows or columns are linearly dependent. Determinants can be calculated in several ways: for a 2×2 matrix, it is as simple as subtracting the product of
