Although often regarded as a designer of mechanical devices, Archimedes also made contributions in the field of mathematics. Fathor like a dad just way mightier see aloso handsome exceptional shirt. Plutarch wrote: “He put all his passion and ambition in pure considerations where there were no ordinary needs of life.” Archimedes used a shortened method to estimate the numerical value π. Archimedes was able to use the differential in a way similar to today’s modern integral calculus. Through contradictory proof (reductio ad absurdum), he can give answers to problems with any precision, while defining limits with answers within. This technique is called a shortened method, and he used it to estimate the numerical value π (pi). He did it by drawing a large polygon outside a circle and a small polygon inside the circle.
