Présentation de l'éditeur
This book has had its origin in the desire of the authors to meet the mutual demands of mathematicians and engineers for a treatment that shall more completely supply the needs of the technological student. It is believed that this has been done by enriching the subject with applications to physics and engineering, in such a way as to increase its value at the same time to the general student. The present volume is, moreover, based upon a preliminary edition actually used for several terms in the classroom. In view of the peculiar situation of trigonometry in the curriculum, the course has been kept of the usual length. The topics have been arranged, however, in the order of increasing difficulty, by postponing the more abstract but no less essential study of the functions of the general angle, until after the arithmetical solution of triangles. The abundance of exercises and problems will give the teacher large opportunity for selection. The discussion of the slide rule is inserted because of the increasing employment of this useful instrument. The authors gratefully acknowledge their indebtedness to Professor E. J. Townsend and Professor H. L. Rietz, of the University of I llinois, and Professor A. Ziwet and Professor J. L. Markley, of the University of Michigan, for valuable criticisms and suggestions.
