Book Summary of Linear Algebra And Its Application
Linear algebra is relatively easy for students during the early stages of the course, when the
material is presented in a familiar, concrete setting. But when abstract concepts are introduced,
students often hit a brick wall. Instructors seem to agree that certain concepts (such as linear
independence, spanning, subspace, vector space, and linear transformations), are not easily
understood, and require time to assimilate. Since they are fundamental to the study of linear
algebra, students understanding of these concepts is vital to their mastery of the subject. Lay
introduces these concepts early in a familiar, concrete R n setting, develops them gradually, and
returns to them again and again throughout the text. Finally, when discussed in the abstract,
these concepts are more accessible
