In North America, Stewart’s books outsell all other calculus textbooks combined. Now, Stewart’s name is also associated with his new home, a spectacular structure of graceful curves, wood, and glass that has put his Toronto neighborhood on the international architectural map. Named Integral House, the innovative building melds with the side of a wooded ravine. Its five floors encompass an airy performance space, where cham- ber groups have already performed to audiences of as many as 150 people. A Canadian, Stewart grew up in Toronto. In high school, he was interested in all subjects, including languages, history, Mathematician and author James Stewart stands in front of and English. He also played the violin and had a passion for a selection of the many editions of his calculus textbooks. music.

I don’t know what my fellow students thought, but I thought that was fascinating.” Unable to make up his mind about which direction to take, Stewart followed the advice of his high school guidance councilor to pur- sue science, and he went into the demanding mathematics, physics, and chemistry program at the University of Toronto. At the end of his second year, however, he came very close to switching from mathematics to music. “In the end, I decided not to because I thought it would be better to be a mathematician whose hobby is music than a musician whose hobby is mathematics,” Stewart says. Interested in specializing in analysis, Stewart went to Stanford University for his master’s degree. “At that time, virtually the entire math faculty at Stanford consisted of analysts,” he says. “And there was the appeal of California weather.” From the street, only two levels of the five-level house are visible, in- Stewart came back to the University of Toron- cluding a top floor sheathed in curved, frosted glass.

  • Verified Interactive Computation of Definite Integrals
    Verified Interactive Computation of Definite Integrals Runqing Xu1;2 ID , Liming Li1 ID , Bohua Zhan1;2(B) ID 1SKLCS, Institute of Software, Chinese Academy of Sciences, Beijing, China 2University of Chinese Academy of Sciences, Beijing, China fxurq, lilm, [email protected] Abstract. Symbolic computation is involved in many areas of math- ematics, as well as in analysis of physical systems in science and en- gineering. Computer algebra systems present an easy-to-use interface for performing these calculations, but do not provide strong guarantees of correctness. In contrast, interactive theorem proving provides much stronger guarantees of correctness, but requires more time and exper- tise. In this paper, we propose a general framework for combining these two methods, and demonstrate it using computation of definite integrals. It allows the user to carry out step-by-step computations in a familiar user interface, while also verifying the computation by translating it to proofs in higher-order logic. The system consists of an intermediate lan- guage for recording computations, proof automation for simplification and inequality checking, and heuristic integration methods. A prototype is implemented in Python based on HolPy, and tested on a large collec- tion of examples at the undergraduate level. Keywords: Symbolic integration, User interface, Proof automation 1 Introduction Symbolic computation is an important tool in mathematics, science, and engi- neering. It forms a key part of many mathematical proofs. On the engineering side, justifications for the design of signal processing and control systems con- tain extensive symbolic computations [6,33], involving derivatives and integrals, Laplace and Fourier transforms, and various special functions.

  • Gamma and Beta Integrals 1 Gamma Function
    Gamma and Beta Integrals Jeffery Yu May 30, 2020 This article presents an overview of the gamma and beta functions and their relation to a variety of integrals. We will touch on several other techniques along the way, as well as allude to some related advanced topics. However, we will not worry about the finer details of convergence, and all given integrals do convergence for the given bounds. Most of these kinds of integrals that would occur on an integration bee are solvable via other traditional methods too, but our methods will often provide quicker and more methodical solutions. The prerequisite is standard single-variable integration, primarily of polynomial, exponential, and trigonometric functions, along with integration by substitution (reverse chain rule, often called u-substitution), integration by parts (reverse product rule), and improper integrals. There are a couple derivations involving partial derivatives or double integrals, but otherwise multivariable calculus is not essential. 1 Gamma Function Z 1 Our study of the gamma function begins with the interesting property xne−x dx = n! for nonnegative 0 integers n. 1.1 Two derivations The difficulty here is of course that xne−x does not have a nice antiderivative. We know how to integrate polynomials xn, and we know how to integrate basic exponentials e−x, but their product is annoying. Let's consider some small cases first. If n = 0, then we have the familiar integral Z 1 Z a a −x −x −x −a e dx = lim e dx = lim −e = lim (1 − e ) = 1: 0 a!1 0 a!1 0 a!1 If n = 1, then we might recognize it as a typical integration by parts example: Z 1 1 Z 1 −x −x −x xe dx = (−xe ) − −e dx = 1: 0 0 0 Note that the xe−x vanishes at the upper limit due to the e−x and at the lower limit due to the x.
