PREFACE. THE PURPOSE of this book is to explain the rudiments of Algebra and Trigonometry to artisans and others, who may wish to be acquainted with them so far as to make the computations which arise in practice, and to read books in which science is treated mathematically. It is my hope that a student who masters this book and works its examples will find himself able to solve a large number of the questions which applied science raises, and to perform all the ordinary calculations which logarithms assist, and that he will find himself in possession of a trustworthy and available power, although, so far as I conduct him, he will have entered but a small portion of the wide field of modern analysis. The Examples in this book are taken, with a few exceptions, from examination papers publicly accessible. The reader who has no previous knowledge of the subjects of this work, is recommended to omit for a time the following articles :— Algebra.-123-125. 255-260. 262–287. Trigonometry.-Chap. IV. 117-119. 123-127. 130-132. 134 to the end of the chapter. 156 to the end. OSPRINGE VICARAGE: January 4, 1871. W. N. GRIFFIN. |
