Excerpt from Plane and Spherical Trigonometry: An Elementary Text-Book

Carefully selected exercises are given at the end of almost every article. In solving triangles, the natural functions are used where the solution may be obtained easily Without the aid of logarithms. This method has been followed because, where logarithms are used exclu sively, the student often does not know the meaning of the Operation he is performing. The subject of trigono metric equations, which is usually accorded little atten tion, is here given in a separate chapter, for it is thought that in no other way can the student acquire so good a knowledge of general principles or so great skill in applying the formulas.
