A Course in Linear Algebra by David B. Damiano

By David B. Damiano

Suitable for complex undergraduates and graduate scholars, this article deals an entire creation to the elemental techniques of linear algebra. fascinating and encouraging in its procedure, it imparts an figuring out of the subject's logical constitution in addition to the ways that linear algebra presents strategies to difficulties in lots of branches of mathematics.
The authors outline basic vector areas and linear mappings on the outset and base all next advancements on those techniques. This process presents a ready-made context, motivation, and geometric interpretation for every new computational process. Proofs and summary problem-solving are brought from the beginning, providing scholars a right away chance to perform utilising what they have discovered. every one bankruptcy includes an creation, precis, and supplementary workouts. The textual content concludes with a couple of important appendixes and recommendations to chose exercises.

Since this is true for all v E Span (5, U S2), we have Span(Si U S2) C W, + W2. Combining the two parts of the proof, we have the claim. ■ We now show that, in general, the sum of two subspaces is also a subspace. 9) Theorem . Let W, and W2 be subspaces of a vector space V. Then Wi + W2 is also a subspace of V. Proof: It is clear that W, + W2 is nonempty, since Wt and W2 are nonempty. Let x. y be any two vectors in W, + W2 and let c G R. Since x and y G W, + WL, we can write x = X| + x2. y = y, + y2, where x,.
