I'm in an abstract linear algebra course right now, and the prof has explicitly stated that we are allowed to have a supplementary text for practice, but most of the HW would be written by him. With that said, I am trying to pick one of the 3 following: An international edition of Linear Algebra, by Friedberg, Insel, Spence, 4th Ed. Linear Algebra by Georgi E. Shilov Linear Algebra Done Right by Sheldon Axler. I realize that the pitfalls of one book could be accomodated for by referring to a different book, but if you had to pick one of the three, which would it be? The cheapest I can find the Axler book for is $28. I could get both the int'l ed. of Friedberg along with the Shilov book for $30 though. Thoughts?
