Eigenvalues and Eigenvectors

Special properties of a matrix lead to special eigenvalues and eigenvectors. That is a major theme of this chapter (it is captured in a table at the very end). 286 Chapter 6.

4.3 Least Squares Approximations

4.3. Least Squares Approximations 221 Figure 4.7: The projection p DAbx is closest to b,sobxminimizes E Dkb Axk2. In this section the situation is just the opposite. There are no solutions to Ax Db. Instead of splitting up x we are splitting up b. Figure 4.3 shows the big picture for least squares. Instead of Ax Db we solve Abx Dp.

V7. Laplace’s Equation and Harmonic Functions

A. Existence. Does there exist a φ(x,y) harmonic in some region containing Cand its interior R, and taking on the prescribed boundary values? B. Uniqueness. If it exists, is there only one such φ(x,y)? C. Solving. If there is a unique φ(x,y), determine it by some explicit formula, or approximate it by some numerical method.

The Limit of a Sequence - MIT Mathematics

“obvious” using the definition of limit we started with in Chapter 1, but we are committed now and for the rest of the book to using the newer Definition 3.1 of limit, and therefore the theorem requires proof. Theorem 3.2B {an} increasing, L = liman ⇒ an ≤ L for all n; {an} decreasing, L = liman ⇒ an ≥ L for all n. Proof.
