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 of matrices and determinants, exploring their definitions, properties, and methods of computation. The goal of this chapter is to provide you with a solid understanding of these concepts and equip you with the tools to apply them effectively in solving problems in linear algebra and other areas of mathematics.Learning Objectives: By the end of this chapter, you should be able to: Define matrices and understand their various types (e.g., square, rectangular, diagonal, identity, etc.). Perform basic matrix operations such as addition, subtraction, multiplication, and scalar multiplication.
