The same plan has been adopted as in the Algebra for Beginners: the subject is discussed in short chapters, and a collection of examples is attached to each chapter. Many of these examples are original and have been constructed with reference to the most important points and to the usual difficulties of beginners; the rest have been derived from College and University Examination Papers. Especial attention has been paid to the numerical calculations which occur in Trigonometry, in order that the work may be suitable for those who wish to confine themselves to the practical solution of triangles, as well as for those who intend to advance in the study of mathematics. The subject is arranged in the order which appears most convenient for beginners; an acquaintance with the books of Euclid which are usually read, and with the rudiments of Algebra, being all that is assumed.
