Vector Spaces,symbols to denote certain sets. For instance we denote by . the set of all numbers. To say that “x is a number” or that “x is an element of .. amounts to the same thing. The set of n-tuples of numbers will be denoted by . Thus . is an element of .. and . is an n-tuple“ mean the same thing. Instead o壮丽的去 发表于 2025-3-22 02:26:57
Linear Mappings,portant. A good deal of mathematics is devoted to reducing questions concerning arbitrary mappings to linear mappings. For one thing, they are interesting in themselves, and many mappings are linear. On the other hand, it is often possible to approximate an arbitrary mapping by a linear one, whose s老人病学 发表于 2025-3-22 05:36:52

Eigenvectors and Eigenvalues,tic polynomial. In §3, we also get an elegant mixture of calculus and linear algebra by relating eigenvectors with the problem of finding the maximum and minimum of a quadratic function on the sphere. Most students taking linear algebra will have had some calculus, but the proof using complex number担心 发表于 2025-3-22 14:57:17
