Printed in the United States of America Firsl Printing Previous editions copyright, 1934, 1947, by The Marmillan Company Library of Congress catalog card number: 57-7909 PREFACE TO THE FIRST EDITION The first study of any portion of mathematics should not be done from a synopsis of compact results, such as this collection. The references, although they are far from complete, will be helpful, it is hoped, in showing where the derivation of the results is given or where further similar results may be found. A list of numbered references is given at the end of the book. These are referred to in the text as “Ref. 7, p. 32,” etc., the page num- ber being that of the publication to which reference is made. Letters are considered to represent real quantities unless other- wise stated. Where the square root of a quantity is indicated, the positive value is to be taken, unless otherwise indicated. Two vertical lines enclosing a quantity represent the absolute or numerical value of that quantity, that is, the modulus of the quantity. The absolute value is a positive quantity. Thus, log I- 31 = log 3. The constant of integration is to be understood after each integral. The integrals may usually be checked by differentiat- ing. In algebraic expressions, the symbol log represents natural or Napierian logarithms, that is, logarithms to the base e. When any other base is intended, it will be indicated in the usual .~ manner. When an integral contains the logarithm of a certain quantity, integration should not be carried from a negative to a positive value of that quantity. If the quantity is negative, the logarithm of the absolute value of the quantity may be used, since log (- 1) = (2k + 1) ?ri will be part of the constant of integration (see 409.03). Accordingly, in many cases, the loga- rithm of an absolute value is shown, in giving an integral, so as to indicate that it applies to real values, both positive and negative. Inverse trigonometric functions are to be understood as refer- ring to the principal values. Suggestions and criticisms as to the material of this book and as to errors that may be in it, will be welcomed. v vi PREFACE The author desires to acknowledge valuable suggestions from Professors P. Franklin, W. H. Timbie, L. F. Woodruff, and F. S. Woods, of Massachusetts Institute of Technology. H. B. DWIGHT. CAMBRIDGE, MASS. December, 1933. PREFACE TO THE SECOND EDITION A considerable number of items have been added, including groups of integrals involving (ax2 + 62~ + fP2, r+kx and a + l cos 2 ) also additional material on inverse functions of complex quanti- ties and on Bessel functions. A probability integral table (No. 1045) has been included. It is desired to express appreciation for valuable suggestions from Professor Wm. R. Smythe of California Institute of Tech- nology and for the continued help and interest of Professor Philip Franklin of the Department of Mathematics, Massachusetts In- stitute of Technology. HERBERT B. DWIGHT. CAMBRIDGE, MASS. PREFACE TO THE THIRD EDITION In this edition, items 59.1 and 59.2 on determinants have been added. The group (No. 512) of derivatives of inverse trigo- nometric functions has been made more complete. On page 271 material is given, suggested by Dr. Rose M. Ring, which extends the tables of ez and e-z considerably, and is convenient when a calculating machine is used. Tables 1015 and 1016 of trigonometric functions of hundredths of degrees are given in this edition on pages 220 to 257. When calculating machines are used, the angles of a problem are PREFACE vii usually given in decimals. A great many trigonometric formulas involve addition of angles or multiplication of them by some quantity, and even when the angles are given in degrees, minutes, and seconds, to change the values to decimals of a degree gives the advantages that are always afforded by a decimal system compared with older and more awkward units. In such cases, the tables in hundredths of degrees are advantageous. HERBERT B.

  • The Enigmatic Number E: a History in Verse and Its Uses in the Mathematics Classroom
    To appear in MAA Loci: Convergence The Enigmatic Number e: A History in Verse and Its Uses in the Mathematics Classroom Sarah Glaz Department of Mathematics University of Connecticut Storrs, CT 06269 [email protected] Introduction In this article we present a history of e in verse—an annotated poem: The Enigmatic Number e . The annotation consists of hyperlinks leading to biographies of the mathematicians appearing in the poem, and to explanations of the mathematical notions and ideas presented in the poem. The intention is to celebrate the history of this venerable number in verse, and to put the mathematical ideas connected with it in historical and artistic context. The poem may also be used by educators in any mathematics course in which the number e appears, and those are as varied as e's multifaceted history. The sections following the poem provide suggestions and resources for the use of the poem as a pedagogical tool in a variety of mathematics courses. They also place these suggestions in the context of other efforts made by educators in this direction by briefly outlining the uses of historical mathematical poems for teaching mathematics at high-school and college level. Historical Background The number e is a newcomer to the mathematical pantheon of numbers denoted by letters: it made several indirect appearances in the 17 th and 18 th centuries, and acquired its letter designation only in 1731. Our history of e starts with John Napier (1550-1617) who defined logarithms through a process called dynamical analogy [1]. Napier aimed to simplify multiplication (and in the same time also simplify division and exponentiation), by finding a model which transforms multiplication into addition.

  • Introduction to Analytic Number Theory the Riemann Zeta Function and Its Functional Equation (And a Review of the Gamma Function and Poisson Summation)
    Math 229: Introduction to Analytic Number Theory The Riemann zeta function and its functional equation (and a review of the Gamma function and Poisson summation) Recall Euler’s identity: ∞ ∞ X Y X Y 1 [ζ(s) :=] n−s = p−cps = . (1) 1 − p−s n=1 p prime cp=0 p prime We showed that this holds as an identity between absolutely convergent sums and products for real s > 1. Riemann’s insight was to consider (1) as an identity between functions of a complex variable s. We follow the curious but nearly universal convention of writing the real and imaginary parts of s as σ and t, so s = σ + it. We already observed that for all real n > 0 we have |n−s| = n−σ, because n−s = exp(−s log n) = n−σe−it log n and e−it log n has absolute value 1; and that both sides of (1) converge absolutely in the half-plane σ > 1, and are equal there either by analytic continuation from the real ray t = 0 or by the same proof we used for the real case. Riemann showed that the function ζ(s) extends from that half-plane to a meromorphic function on all of C (the “Riemann zeta function”), analytic except for a simple pole at s = 1. The continuation to σ > 0 is readily obtained from our formula ∞ ∞ 1 X Z n+1 X Z n+1 ζ(s) − = n−s − x−s dx = (n−s − x−s) dx, s − 1 n=1 n n=1 n since for x ∈ [n, n + 1] (n ≥ 1) and σ > 0 we have Z x −s −s −1−s −1−σ |n − x | = s y dy ≤ |s|n n so the formula for ζ(s) − (1/(s − 1)) is a sum of analytic functions converging absolutely in compact subsets of {σ + it : σ > 0} and thus gives an analytic function there.

  • Generating Highly Accurate Values for All Trigonometric Functions
    GENERATING HIGHLY ACCURATE VALUES FOR ALL TRIGONOMETRIC FUNCTIONS INTRODUCTION: Although hand calculators and electronic computers have pretty much eliminated the need for trigonometric tables starting about sixty years ago, this was not the case back during WWII when highly accurate trigonometric tables were vital for the calculation of projectile trajectories. At that time a good deal of the war effort in mathematics was devoted to building ever more accurate trig tables some ranging up to twenty digit numerical accuracy. Today such efforts can be considered to have been a waste of time, although they were not so at the time. It is our purpose in this note to demonstrate a new approach for quickly obtaining values for all trigonometric functions exceeding anything your hand calculator can achieve. BASIC TRIGNOMETRIC FUNCTIONS: We begin by defining all six basic trigonometric functions by looking at the following right triangle- The sides a,b, and c of this triangle satisfy the Pythagorean Theorem- a2+b2=c2 we define the six trig functions in terms of this triangle as- sin()=b/c cos( )=a/c tan()=b/a csc()=c/b sec()=c/a) cot()=b/a From Pythagorous we also have at once that – 1 sin( )2 cos( )2 1 and [1 tan( )2 ] . cos( )2 It was the ancient Egyptian pyramid builders who first realized that the most important of these trigonometric functions is tan(). Their measure of this tangent was given in terms of sekels, where 1 sekhel=7. Converting each of the above trig functions into functions of tan() yields- tan( ) 1 sin( ) cos( ) tan( ) tan( ) 1 tan( )2 1 tan( )2 1 tan( )2 1 csc( ) sec( ) 1 tan( )2 cot( ) tan( ) tan( ) In using these equivalent definitions one must be careful of signs and infinities appearing in the approximations to tan().

COFFEY, OLIVIER ESPINOSA, CHRISTOPH KOUTSCHAN, DANTE V. MANNA, AND VICTOR H. MOLL (Communicated by Ken Ono) Abstract. Properties of the integral of powers of log Γ(x) from 0 to 1 are con- sidered. Analytic evaluations for the first two powers are presented. Empirical evidence for the cubic case is discussed. 1. Introduction The evaluation of definite integrals is a subject full of interconnections of many parts of mathematics. Since the beginning of Integral Calculus, scientists have developed a large variety of techniques to produce magnificent formulae. A partic- ularly beautiful formula due to J. L. Raabe [12] is 1 Γ(x + t) (1.1) log √ dx = t log t − t, for t ≥ 0, 0 2π which includes the special case 1 √ (1.2) L1 := log Γ(x) dx =log 2π. 0 Here Γ(x)isthegamma function defined by the integral representation ∞ (1.3) Γ(x)= ux−1e−udu, 0 for Re x>0. Raabe’s formula can be obtained from the Hurwitz zeta function ∞ 1 (1.4) ζ(s, q)= (n + q)s n=0 via the integral formula 1 t1−s (1.5) ζ(s, q + t) dq = − 0 s 1 coupled with Lerch’s formula ∂ Γ(q) (1.6) ζ(s, q) =log √ . ∂s s=0 2π An interesting extension of these formulas to the p-adic gamma function has recently appeared in [3].

Using this relation, we, then proved, x approximates to double the sum of odd harmonic series having first and last terms 1/3 and 1/(2x - 1) respectively. Thereafter, not limiting to consecutive numbers ratios, we extended its applicability to all the real numbers. Based on these relations, we, then derived a formula for approximating the value of Factorial x.We could also approximate the value of Euler-Mascheroni constant. In these derivations, we used only and only elementary functions, thus this paper is easily comprehensible to students and scholars alike.

    NOTES ON RIEMANN’S ZETA FUNCTION DRAGAN MILICIˇ C´ 1. Gamma function 1.1. Definition of the Gamma function. The integral ∞ Γ(z)= tz−1e−tdt Z0 is well-defined and defines a holomorphic function in the right half-plane {z ∈ C | Re z > 0}. This function is Euler’s Gamma function. First, by integration by parts ∞ ∞ ∞ Γ(z +1)= tze−tdt = −tze−t + z tz−1e−t dt = zΓ(z) Z0 0 Z0 for any z in the right half-plane. In particular, for any positive integer n, we have Γ(n) = (n − 1)Γ(n − 1)=(n − 1)!Γ(1). On the other hand, ∞ ∞ Γ(1) = e−tdt = −e−t = 1; Z0 0 and we have the following result. 1.1.1. Lemma. Γ(n) = (n − 1)! for any n ∈ Z. Therefore, we can view the Gamma function as a extension of the factorial. 1.2. Meromorphic continuation. Now we want to show that Γ extends to a meromorphic function in C. We start with a technical lemma. Z ∞ 1.2.1. Lemma. Let cn, n ∈ +, be complex numbers such such that n=0 |cn| converges. Let P S = {−n | n ∈ Z+ and cn 6=0}. Then ∞ c f(z)= n z + n n=0 X converges absolutely for z ∈ C − S and uniformly on bounded subsets of C − S. The function f is a meromorphic function on C with simple poles at the points in S and Res(f, −n)= cn for any −n ∈ S. 1 2 D. MILICIˇ C´ Proof. Clearly, if |z| < R, we have |z + n| ≥ |n − R| for all n ≥ R.
