THE history of Wentworth's Geometry is a study in evolution. It was the corner stone on which was built a now famous mathematical series. Its arrangement and plan have always appealed to the eager student as well as to the careful teacher. It was the first to advocate the doing of original exercises by the pupils to give them independence and clear thinking. As occasion has offered, Professor Wentworth has revised the book in the constant endeavor to improve it and move it a little nearer the ideal. The present edition is a close approach to this end. It represents the consensus of opinion of the leading mathematical teachers of the country. It stands for exact scholarship, great thoroughness, and the highest utility to both the student and the teacher. In this new edition different kinds of lines are used in the figures, to indicate given, resulting, and auxiliary lines. These render the figures much clearer. In the Solid Geometry finely engraved woodcuts of actual solids have been inserted, for the purpose of aiding the pupil in visualization. They give just the necessary assistance. The treatment of the Theory of Limits is believed to be the best presentation of the subject in any elementary geometry. |
