Présentation de l'éditeur
It has been the authors aim to treat the subject according to the latest and most approved methods. The book is designed for the use of colleges, technical schools, normal schools, secondary schools, and for those who take up the subject witho $the aid of a teacher. Special attention has been paid to the requirements of the College Entrance Board. The book contains more material than is required for some first courses in Trigonometry, but the matter has been so arranged that the teacher can make such omissions as will suit his particular needs. The trigonometric functions are denned as ratios; first for acute angles in right triangles, and then these definitions are extended to angles in general by means of coordinates. The student is first taught to use the natural functions of acute angles in the solution of simple problems involving right triangles. Attention is called to the methods shown in 23-29 for the reduction of functions of angles outside of the first quadrant. In general, the first examples given under each topic are worked out, making use of the natural functions. A large number of carefully graded exercises are given, and the processes involved are summarized into working rules wherever practicable. Illustrative examples are worked out in detail under each topic. Logarithms are introduced as a separate topic, and attention is called to the fact that they serve to minimize the labor of computation. Granville s Four-P lace Tables of Logarithms is used. While no radical changes in the usual arrangement of logarithmic tables have been made, several improvements have been effected which greatly facilitate logarithmic computations. Particularly important is the fact that the degree of accuracy which may be expected in a result found by the aid of these tables is clearly indicated. Under each case in the solution of triangles are given two complete se

A review from The American Mathematical Monthly, Volume 16, 1909:
The subject of Trigonometry as presented in this book is in accordance with the latest and most approved methods. Trigonometric Functions are defined as ratios, first for angles less than a right angle and then extended to angles in general. A valuable feature of the book is the fact that the degree of accuracy which may be expected in a result found by the aid of the tables is clearly indicated. In the treatment of oblique spherical triangles the author makes use of the Principle of Duality, whereby nearly half of the work usually required in deriving the standard formulae is saved and the usual six cases are reduced to three. A large number of illustrative problems are worked out under each topic and a large number of well graded exercises are given. The typography and mechanical execution of the book are very beautiful and artistic.
