David Poole's innovative LINEAR ALGEBRA: A MODERN INTRODUCTION, 4e emphasizes a vectors approach and better prepares students to make the transition from computational to theoretical mathematics. Balancing theory and applications, the book is written in a conversational style and combines a traditional presentation with a focus on student-centered learning. Theoretical, computational, and applied topics are presented in a flexible yet integrated way. Stressing geometric understanding before computational techniques, vectors and vector geometry are introduced early to help students visualize concepts and develop mathematical maturity for abstract thinking. Additionally, the book includes ample applications drawn from a variety of disciplines, which reinforce the fact that linear algebra is a valuable tool for modeling real-life problems.
My first linear algebra book, this was the textbook used for my Maths course in university. Overall, had a good time with this one, had a good balance of theory and application (though I didn't care for applications all that much).
C1 - Vectors, nothing much to add onto what I already know C2 - Systems of Linear Equations, again nothing new, but it did solidify my understanding of RREF and Gauss-Jordan C3 - Matrices, fun chapter for proofs. Nothing new though C4 - Eigenvalues and Eigenvectors, pretty interesting especially with all the theory behind it. C5 - Orthogonality, interesting and quite short. C6 - Vector Spaces, probably my favourite one, this generalises vector operations to not just vectors, but also matrices and functions. C7 - Distance and Approximation, I like the first half about norms and inner products, even more generalisation of what we already know. The second half is more on applications so it fell a bit flat but I still like least-squares.
This is easily the best STEM textbook I've ever read. The texts are actually written by humans who speak English, rather than by some minimally embodied intellects, as in the case of so many other STEM textbooks. But there are more positive traits: not only are there side notes on the etymology of certain mathematical terms, but there are also brief introductions of famous mathematicians who discovered the theorem or property being discussed. As for hard content, this book is very systematic and well organised. The level of knowledge is a bit too basic, and it never really goes very advanced even by the end, but it nevertheless provides an adequate mathematical foundation for one to have a deeper comprehension of the principles of relevant areas in physics. A useful tool to have at hand.
Very comprehensive explanations accompanied by plenty of examples and proofs. The exercises are a great way to practice but there are answers only to odd problems (for teaching purposes), so one often has to look elsewhere if they want to check their solutions.
I had a horrible linear algebra teacher so this book taught me everything I needed to know. Was it perfect? No, but it was comprehensive and I think an excellent source for learning linear algebra.
