Omar Khayyams Geometric Solution Mugs

Description: This scientific diagram shows a parabola y = x² and a circle intersecting on a coordinate grid, the intersection giving the root x = 2 of the cubic equation x³ + x = 10, on a deep dark background. The Persian mathematician and poet Omar Khayyam (1048–1131) solved cubic equations geometrically by intersecting conic sections, a remarkable step between Greek geometry and modern algebra. A gift idea for mathematicians, math teachers and engineers, and a quiet statement piece for a study, classroom or office wall.
