Excerpt from Solutions of the Examples in Hall and Knight's Elementary Trigonometry IN preparing this Key two objects have been kept in View. It is intended first to save the time and lighten the work of teachers, and secondly to afford help to those who study Mathematics without the guidance of a teacher. Accordingly the solutions have generally been given in the most simple and natural manner, with frequent reference to the text and examples in the Elementary Trigonometry. In particular, the solutions which involve logarithmic work have been presented in the fullest detail, so that with the help of the Key, a teacher will be able very readily to discover and correct mistakes in the work of his pupils. For very many of the solutions I am indebted to Mr H. C. Playne of Clifton College, and my thanks are due to him for valuable help all through the book.
