Theory of functions of a real variable.

In Chapter II I do the basics of Hilbert space theory, i.e. what I can do without measure theory or the Lebesgue integral. The hero here (and perhaps for the first half of the course) is the Riesz representation theorem. Included is the spectral theorem for …

A Mathematical Theory of Communication

J. W. Tukey. A device with two stable positions, such as a relay or a flip-flop circuit, can store one bit of information. N such devices can store N bits, since the total numberof possible states is 2N and log 2 2 N = N. If the base 10 is used the units may be called decimal digits. Since log2 M = log10 M log10 2 = 3: 32log10 M;

Again, we’re going to rewrite this using new symbols. Let mean multiplication, and let e= 1, a= 2, b= 4, and c= 3. Then, the multiplication table for (Z=5Z) looks like e a b c e e a b c a a b c e b b c e a c c e a b Notice that this is exactly the same as the table for addition on Z=4Z!

B= S 1v. Theorem: If T(x) = Ax is a linear map and S is the matrix from a basis change, then B = S 1AS is the matrix of T in the new basis B. Proof. Let y = Ax. The statement [y] B= B[x] Bcan be written using the last theorem as S 1y = BS 1x so that y = SBS 1x. Combining with y = Ax, this gives B = S 1AS. 5.4. If two matrices A;B satisfy B = S ...

to Yoneda’s lemma, this property determines the space Zup to homotopy equivalence. Moreover, since the functor X7!K(X) takes values in the category of commutative rings, the topological space Z is automatically a commutative ring object in the homotopy category H of topological spaces.

Lecture 9: Partial derivatives

Lecture 9: Partial derivatives If f(x,y) is a function of two variables, then ∂ ∂x f(x,y) is defined as the derivative of the function g(x) = f(x,y), where y is considered a constant. It is called partial derivative of f with respect to x. The partial derivative with respect to y is defined similarly. We also use the short hand notation ...

An equidistant projection maintains consistency of scale for certain distances. An azimuthal projection retains certain accurate directions. Cartographers often use a geometric object to illustrate how a map projection can be constructed. For example, by placing a cylinder tangent to a lighted globe, a projection can be made by tracing the lines of

Three-Dimensional Coordinate Systems

Plotting Points in xyz-space Graphing in xyz-space can be di cult because, unlike graphing in the xy-plane, depth perception is required. To simplify plotting of points, one can make use of projections onto the coordinate planes. The projection of a point (x;y;z) onto the xy-plane is obtained by connecting the point to
