Spherical Trigonometry: For Colleges and Secondary Schools. E-book. Formato PDF. This book contains little more than what is required for the solution of spherical triangles and related simple practical problems. The articles on spherical geometry are necessary for those who have not already studied that subject; for others, they provide a useful review. More than usual attention has been given to the measurement of solid angles. The explana tions in connection with the astronomical problems are somewhat fuller than is customary in elementary text-books on spherical trigonometry.
