PLANE TRIGONOMETRY, PART I

This book is a fairly complete elementary text-book on Plane Trigonometry, suitable for Schools and the Pass and Junior Honour classes of Universities. In the higher portion of the book I have endeavored to present to the student, as simply as possible, the modern treatment of complex quantities, and I hope it will be found that he will have little to unlearn when he commences to read treatises of a more difficult character.

As Trigonometry consists largely of formulae and the applications thereof, I have prefixed a list of the principal formulae which the student should commit to memory. These more important formulae are distinguished in the text by the use of thick type. Other formulae are subsidiary and of less importance.
