Book excerpt: Excerpt from The Elements of Spherical Trigonometry IN the following pages the author has endeavored to make the subject of Spherical Trigonometry plain to beginners. In order to do this, considerable space has been devoted to the treatment of the right-angled spherical triangle, and to the consideration of the ob lique-angled spherical triangle, by means of diagrams, before applying the principles of trigonometry to each. It is believed that in this way the student will become familiar with the magnitudes about which his calcula tions are made, and thus will be unwilling to use sym bols and numbers in formulas without having clear ideas of what these symbols and numbers represent.
