Kimberling Sangaku Problem Sangaku problems, often written "san gaku," are geometric problems of the type found on devotional mathematical wooden tablets ("sangaku") were hung under the roofs of shrines or temples in Japan during two centuries of schism from the west (Fukagawa and Pedoe 1989). During the time of isolation, Japanese mathematicians developed their own "traditional mathematics," which, in the 1850s, began giving way to western methods. There were also changes in the script in which mathematics was written and, as a result, few people now living know how to interpret the historic tablets (Kimberling). Japanese mathematicians represented in sangaku include Seki Kowa (1642-1708), Ajima Chokuen (also called Naonobu; 1732-1798), and Shoto Kenmotu (1790-1871). Sangaku problems typically involve mutually tangent circles or tangent spheres , with specific examples including the properties of the Ajima-Malfatti points Japanese theorem , and Kenmotu point SEE ALSO: Ajima-Malfatti Points Casey's Theorem Circle Inscribing Cylinder-Sphere Intersection ...

Sangaku Problems Japanese Theorem Let a convex cyclic polygon be triangulated in any manner, and draw the incircle to each triangle so constructed. Then the sum of the inradii is a constant independent of the triangulation chosen. This theorem can be proved using Carnot's theorem . In the above figures, for example, the inradii of the left triangulation are 0.142479, 0.156972, 0.232307, 0.498525, and the inradii of the right triangulation are 0.157243, 0.206644, 0.312037, 0.354359, giving a sum of 1.03028 in each case. According to an ancient custom of Japanese mathematicians, this theorem was a Sangaku problem inscribed on tablets hung in a Japanese temple to honor the gods and the author in 1800 (Johnson 1929). The converse is also true: if the sum of inradii does not depend on the triangulation of a polygon , then the polygon is cyclic SEE ALSO: Carnot's Theorem Cyclic Polygon Incircle Inradius ...

Extractions: RELATED LINKS Of the world's countless customs and traditions, perhaps none is as elegant, nor as beautiful, as the tradition of sangaku , Japanese temple geometry. From 1639 to 1854, Japan lived in strict, self-imposed isolation from the West. Access to all forms of occidental culture was suppressed, and the influx of Western scientific ideas was effectively curtailed. During this period of seclusion, a kind of native mathematics flourished. Devotees of math, evidently samurai, merchants and farmers, would solve a wide variety of geometry problems, inscribe their efforts in delicately colored wooden tablets and hang the works under the roofs of religious buildings. These sangaku , a word that literally means mathematical tablet, may have been acts of homagea thanks to a guiding spiritor they may have been brazen challenges to other worshipers: Solve this one if you can!

Extractions: Answers to Sangaku Problems The original solution to this problem applies the Japanese version of the Descartes circle theorem several times. The answer given here, though, was obtained by using the inversion method, which was unknown to the Japanese mathematicians of that era. Because the method of inversion is generally not taught in American math courses, let us first review the technique and state without proof the results needed to solve the problem. Inversion is an operation generally defined with respect to a circle, call it S , with a radius k and a center T . The point T is called the center of inversion. Let P be any point in the plane containing S , and let TP be the legnth joining points T and P If P' is the inverse of P with respect to S , then In other words, r is the geometric mean of the lengths TP and TP' . The reason is that by construction, triangles TAP' and TAP are similar and so TP/r = r/TP' or TP (TP') = r Not only pointsbut entire figurescan be inverted. Each point P on the original inverts to P' on the inversion. The following four theorems apply to a circle

Abstract: The mathematics developed in Japan during the Edo Period (1603-1867) is called Wasan (Japanese mathematics). Wasan has its roots ancient Chinese mathematics. The concept of angle, however, did not grow up either of ancient Chinese and Japanese mathematics. In the sixteenth century Jesuit missionaries as a part of their propagation activity bought Western scientific knowledge and technology into Ming China which still had been maintaining traditional academic system since ancient time. At that time Western trigonometry was introduced into China, and encounter of different mathematics thought made to mean an opening of new intelligence activities in the history of East Asian mathematics. In 1720 the eighth Shogun Tokugawa Yoshimune permitted the import of Chinese books on Western Calendrical Calculations from Qing China. From this time, openly, Japanese scientists could make to study the Western scientific and technology. It means indirect acceptance of Western knowledge
