A propos du livre

Présentation de l'éditeur

In revising his Plane andS pherical Trigonometry, the author has effected many important improvements. The attention of teachers is specially invited to the following features of the new work: 1. The proofs of the functions of 0, 90 ,180 ,and 270 ;22 to 25. 2. The proofs of the functions of 120 ,135 ,etc.; J27. 3. The method of finding the values of the remaining functions of an angle when the value of any one is given; 28. 4. The proofs of the functions of (A), and (90 +A), in terms of those of .4; 29,30. 5. The method of solution in the examples of 34 and 35. 6. The general demonstration of the formulae for sin (x +y) and cos (a; +2) ;42. 7. The discussion of the line values of the functions, and their application in tracing the changes in the six principal functions of an angle as the angle increases from 0to 360 ;60, 61. 8. The discussion of trigonometric equations in 62. 9. The solution of right triangles by Natural Functions; see Ex. 1, page 54. 10. The discussion of the ambiguous case in the solution of oblique triangles; 117 to 120. 11. The proof of the formulae for the values of xin the cubic equation x-ax-b =0 ,126. 12. The geometrical proof of the important theorems of 133. 13. The demonstration of the formulae for right spherical triangles before those for oblique spherical triangles; see Chapters XI. and XII. 14. The reduction of the number of cases in the complete demonstration of the fundamental theorems for spherical right triangles, to three, by application of the theorems of 133; see 136.

Présentation de l'éditeur

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.
