ON ELEMENTARY TRIGONOMETRY BY THE REV. J. B. LOCK, M.A. FELLOW OF GONVILLE AND CAIUS COLLEGE, CAMBRIDGE; BIBLIOTHEC AUC F82 BODLEIANA London: MACMILLAN AND CO. 1882 [All Rights reserved.] PREFACE. THE present Work on ELEMENTARY TRIGONOMETRY contains that part of the subject which can conveniently be explained without the use of infinite series. It is intended either for class-teaching or for private study. Accordingly the Examples are numerous and for the most part easy. Those which are not original have been selected from the Cambridge and Army Examination Papers of the last few years. The Miscellaneous Examples are somewhat more difficult, and should in most cases be postponed until the student reads the subject for the second time. The order in which the Chapters are read may be varied at the discretion of the Teacher. The last three Chapters are not required in the Previous Examination of Candidates for Honours at Cambridge.
