In mathematics, matrices and determinants are foundational concepts that have wide-ranging applications in fields such as engineering, computer science, economics, physics, and statistics. At their core, matrices provide a way to represent and manipulate data, systems of equations, and linear transformations in a compact and structured manner. Determinants, on the other hand, offer key insights into the properties of matrices, such as whether a system of linear equations has a unique solution or whether a transformation preserves volume and orientation. This chapter delves into the concepts...
