Gregory‚ and the Bible. The first proof I will be talking about is Liu Hui’s. Liu Hui was a Chinese mathematician whose method for proving pi was to find the area of a polygon inscribed in a circle. When the number of sides on the inscribed polygon increased‚ its area became closer to the circumference of a circle and pi. For finding the side length of an inscribed polygon Liu Hui used a simple formula. (13Ma3) To find the side length of an inscribed polygon of 2n sides‚ if the side length of a polygon

Descartes’ Cartesian Circle Descartes’ “Cartesian Circle” has come under fire from countless philosophers because it supposedly commits a logical fallacy with its circular reasoning. In his second Meditation‚ Descartes attempts to prove the existence of God. He states that clear and distinct perception leads to knowledge‚ and that God’s existence is apparent and obvious because of things we have come to perceive as knowledge. Furthermore‚ he asserts that we cannot turn these perceptions into
