Analytic geometry of space
A college textbook on solid analytic geometry by Virgil Snyder and Charles H. Sisam, published by Henry Holt in New York in 1914 for American undergraduate mathematics courses. The 28 line figures show spheres, cones, paraboloids and hyperboloids drawn with labelled X, Y, Z axes, dashed hidden edges and contour ellipses, offering designers a stock of clean geometric wireframes and axis diagrams.
