III. Mathematical Equations & Notes including Trigonometry, (n.d.)

This series consisted of one manila file folder. Certain sections were further broken down into folders determined on natural breaks by content type and blank pages left between them. These notes are predominately on legal-size paper and handwritten in pencil or ink. The papers predominiately consist of mathematical and scientific notes, equations, diagrams, and charts that are undated. Some notes, particularly “Trigonometry” (folder 27), may represent lecture notes or studies of other works.
