Analytic geometry for colleges, universities, and technical schools
A college textbook on analytic geometry by Edward West Nichols, published in Boston by Leach, Shewell & Sanborn in 1892 for university and technical-school students. The 82 line diagrams show conic sections, tangents and normals, coordinate axes and spirals in thin black line on cream paper, with lettered points and dashed construction lines useful as geometric linework or pattern.
