![]() Each number system is examined in terms of its algorithms, its applications, and its mathematical structure. Topics covered include problem solving, sets and functions, numeration systems, whole numbers (including some number theory), and integers. Although only two years of high school mathematics are required, a more complete background including pre-calculus or calculus is desirable. Enrollment is limited to 30 students per section. Simons University of Groningen PO Box 800, 9700 AV Groningen, The Netherlands e-mail: j.l. Class participation is expected and constitutes a significant part of the course grade. Notes on Number Theory and Discrete Mathematics Print ISSN 13105132, Online ISSN 23678275 2022, Volume 28. The course is conducted using a discussion format. Concepts are heavily emphasized with some attention given to calculation and proof. It is required of all students intending to earn an elementary teaching certificate and is taken almost exclusively by such students. This course, together with its sequel Math 489, provides a coherent overview of the mathematics underlying the elementary and middle school curriculum. No credit granted to those who have takend or are enrolled in Math 485. While the main effort will be to establish the foundations of the subject, applications will include the Fast Fourier Transform, the heat equation, the wave equation, sampling, and signal processing.ģ Credits. Topics will include properties of complex numbers, the Discrete Fourier Transform, Fourier series, the Dirichlet and Fejer kernals, convolutions, approximations by trigonometric polynomials, uniqueness of Fourier coefficients, Parseval's identity, properties of trigonometric polynomials, absolutely convergent Fourier series, convergence of Fourier series, applications of Fourier series, and the Fourier transform, including the Poisson summation formula and Plancherel's identity. One approach to solving a second-order linear recurrence is to guess an exponential so. It should be particularly suitable for majors in the sciences and engineering. Sequences arise in many areas of mathematics, including finance. This is an introduction to Fourier Analysis geared towards advanced undergraduate students from both pure and applied areas. The course also can be viewed as a way of deepening one’s understanding of the 100-and 200-level material by applying it in interesting ways. This course is an introduction to Fourier analysis with emphasis on applications. No credit granted to those who have completed or are enrolled in Math 450 or 454. In addition, enough initial elements must be provided so that all subsequent elements of the sequence can be computed by successive applications of the recurrence relation.3 credits. To define a sequence by recursion, one needs a rule, called recurrence relation to construct each element in terms of the ones before it. This is in contrast to the definition of sequences of elements as functions of their positions. Sequences whose elements are related to the previous elements in a straightforward way are often defined using recursion. In mathematical analysis, a sequence is often denoted by letters in the form of a n a_, but it is not the same as the sequence denoted by the expression.ĭefining a sequence by recursion The first element has index 0 or 1, depending on the context or a specific convention. The position of an element in a sequence is its rank or index it is the natural number for which the element is the image. Sequences can be finite, as in these examples, or infinite, such as the sequence of all even positive integers (2, 4, 6. Also, the sequence (1, 1, 2, 3, 5, 8), which contains the number 1 at two different positions, is a valid sequence. ![]() The notion of a sequence can be generalized to an indexed family, defined as a function from an arbitrary index set.įor example, (M, A, R, Y) is a sequence of letters with the letter 'M' first and 'Y' last. Formally, a sequence can be defined as a function from natural numbers (the positions of elements in the sequence) to the elements at each position. ![]() Unlike a set, the same elements can appear multiple times at different positions in a sequence, and unlike a set, the order does matter. The number of elements (possibly infinite) is called the length of the sequence. Like a set, it contains members (also called elements, or terms).

In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
