G. ESTILL. WHEN arithmetic was dropped from the requirements for admission to Yale College, in 1894, the following substitute was adopted: "Plane Geometry (b)-Solution of numerical problems involving the metric system and the use of Logarithms, also as much of the theory of Logarithms as is necessary to explain their use in simple arithmetical operations.-Five-figure tables will be used in the examination." (1896-97 Catalogue.) At the conference on uniform requirements for admission to college, in February, 1896, at Columbia College, representing Harvard, Yale, Princeton, University of Pennsylvania, Columbia, and Cornell, and nearly all the large preparatory schools of the East, the Mathematical Conference voted unanimously to recommend that arithmetic be dropped from the college entrance requirements, and that a knowledge of the metric system and the ability to solve numerical problems in Plane Geometry be required. These two facts account for the writing of this little book. The most of the problems have had class-room test. They add interest to the study of formal geometry. They are helpful, too, in making clear, and fastening in the memory, the principles and propositions of formal geometry. They enforce the practical application of truths |
