![]() ![]() In his solution, he stated, without proof, three preliminary propositions about parabolas that were known in his time, but are… His method was to fill the region with infinitely many triangles each of whose area he could calculate. ![]() In his famous quadrature of the parabola, Archimedes found the area of the region bounded by a parabola and a chord. Given a parabola in the standard form y = 4ax, corresponding to three points on the parabola, such that the normals at these three points P, Q, R concur at a point M = (h, k), the equation of the circumscribing circle through the three points P, Q, and R provides a tremendous opportunity to illustrate "The Art of Algebraic…Īrchimedes Quadrature of the Parabola: A Mechanical View Applications of device include design of paraboloidal antennas, approximating catenaries on drawings of powerlines or long-wire antennas, and general tracing of parabolas on drawings.ĮRIC Educational Resources Information Center Constancy of critical total distance enforced by maintaining cable in tension. Based on fundamental geometrical construction of parabola. Mechanical device simplifies generation of parabolas of various focal lengths. ![]()
