History

Franklin Classics Trade Press

Before 1854 when George Boole published The Laws of Thought, the subject of 'logic' in the western world was entirely restricted to the study of the Aristotelian syllogism, which was as old as 384-322 BC. In this work, Boole introduces a sort of algebra of propositions with probability. Boole's logic forms the basis for present day Boolean

Calculus Of Finite Differences Fourth Edition

As outspoken in his day as Richard Dawkins or Christopher Hitchens are today, American freethinker and author ROBERT GREEN INGERSOLL (1833-1899) was a notorious radical whose uncompromising views on religion and slavery (they were bad, in his opinion), women's suffrage (a good idea, he believed), and other contentious matters of his era made him a wildly popular orator and critic of 19th-century American culture and public life. As a speaker dedicated to expanding intellectual horizons and celebrating the value of skepticism, Ingersoll spoke frequently on such topics as atheism, freedom from the pressures of conformity, and the lives of philosophers who espoused such concepts. This collection of his most famous speeches includes the lectures: [ "The Gods" (1872) [ "Humboldt" (1869) [ "Thomas Paine" (1870) [ "Individuality" (1873) [ "Heretics and Heresies" (1874)

This is a pre-1923 historical reproduction that was curated for quality. Quality assurance was conducted on each of these books in an attempt to remove books with imperfections introduced by the digitization process. Though we have made best efforts - the books may have occasional errors that do not impede the reading experience. We believe this work is culturally important and have elected to bring the book back into print as part of our continuing commitment to the preservation of printed works worldwide.

A Treatise on the Calculus of Finite Differences

This book was originally published prior to 1923, and represents a reproduction of an important                 historical work, maintaining the same format as the original work. While some publishers have opted to                 apply OCR (optical character recognition) technology to the process, we believe this leads to                 sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and                 does not adequately preserve the historical character of the original artifact. We believe this work is                 culturally important in its original archival form. While we strive to adequately clean and digitally                 enhance the original work, there are occasionally instances where imperfections such as blurred or                 missing pages, poor pictures or errant marks may have been introduced due to either the quality of the                 original work or the scanning process itself. Despite these occasional imperfections, we have brought it                 back into print as part of our ongoing global book preservation commitment, providing customers with                 access to the best possible historical reprints. We appreciate your understanding of these occasional                 imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that                 intended by the original publisher.

Not illustrated. 1872 Excerpt: ...primitive of a singular integral of a differential equation of the second order will itself be a singular solution of that equation, but a singular solution of a singular integral will in general not be a solution at all of that equation. The proof of these propositions will afford an exercise for the student. See Lagrange's Lemons sur le Calcul des Fonctions, Legem 14me of the edition of 1806, or Legon 15me of the edition of 1808. A note by Poisson on page 239 of the edition of 1808 should be consulted; it relates to the second of the above two propositions. See also Lacroix, Traits du Calcul Bifferentiel..., Tome n. pp. 382 and 390. 10. We proceed to inquire how singular integrals may be determined from the differential equation. Expressing as before the first integral involving an arbitrary constant in the form y=f(x,y,y1...ylt,c) (47), we have as the derived equation (df(x, y, y,...#„_„ c) the brackets in the second member indicating that in effecting the differentiation y, y„_2, are to be regarded as functions of x. The differential equation of the nth order is found from (48) by substituting therein, after the differentiation, for c its value in terms of x, y, yx,...y_v given by (47). The result assumes the form yn = (x,y, y,...jO (49). Hence, we have or, representing fix, y, y1...y, c), by /, dyn-t dxdcj dc' Hence, A iog%-=i (50), dx b dc K' provided that the first member be obtained from the differential equation, and the second member from one of its first integrals involving c as arbitrary constant. It is to be borne in mind that in effecting the differentiation with respect to x in the second member, we must regard y, yl,---yn-i as functions of x. Now reasoning as in Chap. vin. since a singular solution makes = 0, it makes its l...

A Treatise on the Calculus of Finite Differences (Classic Reprint)

Calculus ofF inite Differences, particular attention has been paid to the connexion of its methods with those of theD ifferential Calculus a connexion which in some instances involves far more than a merely formal analogy. Indeed the work is in some measure designed as a sequel to my Treatise on Differential Equations. And it has been composed on the same plan. Mr Stirling, ofT rinity College, Cambridge, has rendered me much valuable assistance in the revision of the proofsheets. In offering him my best thanks for his kind aid, I am led to express a hope that the work will be found to bo free from important errors. GEORGE BOOLE.
