Excerpt from A Short Practical Treatise on Spherical Trigonometry: Containing a Few Simple Rules, by Which the Great Difficulties to Be Encountered by the Student in This Branch of Mathematics Are Effectually Obviated
Hipparchus, who flourished about two cen turies after Euclid, and one before the Christian era, is said to have laid the foundation of Spherical Trigonometry. In succeeding ages it was improved by Ptolemy, Theodosius, and others; and much is ascribed to Geber, a learned Spaniard, who lived in the sixteenth century.
