Elements of analytical geometry and the differential and integral calculus
A mathematics textbook by Horatio N. Robinson, published in Cincinnati by J. Ernst in 1856, teaching analytic geometry and calculus to American college and academy students. The 131 figures are small white-line wood engravings on solid black grounds: axes, conic sections, circles, tangents, and lettered construction points, usable as high-contrast geometric marks, diagram fragments, or negative-space line motifs.
