Introduction to Matrices and Determinants for Data and Applied Science

Linear algebra is the mathematical engine behind modern technology, from computer graphics to data analysis. If you want to understand how algorithms process data, you must first understand the fundamental language of matrices and determinants. This text-based course guides you through these essential mathematical structures without overwhelming you with abstract proofs. You will start with the absolute basics, learning the core terminology and definitions of vectors and matrices before moving on to practical operations. By reading through clear, step-by-step explanations and working through written exercises, you will build a strong intuitive and analytical grasp of linear algebra. What you'll learn: - Understand the foundational definitions, dimensions, and types of matrices - Perform matrix addition, subtraction, and scalar multiplication with confidence - Master matrix multiplication and understand its non-commutative nature - Calculate the determinants of 2x2 and 3x3 matrices using systematic methods - Explore the concept of matrix inversion and its role in solving systems of linear equations - Relate matrix operations to modern applications like computer graphics and data transformations This course begins with simple, intuitive definitions and gradually introduces arithmetic operations, properties, and calculation techniques. Each section includes written practice problems with detailed explanations to reinforce your understanding. Designed specifically for beginners, this course requires only basic high school algebra.
