PI (π) One of the oldest and most commonly known and used concepts in mathematics is that of Pi (π). In the earliest of know human civilizations, people realized the importance of finding the exact value of π for practical reasons. Even by todays standards, we still only need to know the exact value of π to a few decimal place values, although that hasn’t stopped mathematicians from pursuing a more accurate representation for its value throughout time.
The earliest know approximations for the value of π have been identified on ancient clay tablets, dated 1900-1650 BC, from the Babylonian civilization which states the value of π as (25/8) = 3.125. and from the Egyptian civilization, from the Rhind Papyrus(1650BC), which approximates the value of π to be (16/9)^2 = 3.1605. Although these earliest of approximations have been proven to be within 1 percent of todays actual know value, it marks the point of obsession for mathematicians to find an exact value for π.
The next advancement in determining a more accurate value didn’t occur for more than another 1000 years. Around 250 BC, the Greek mathematician Archimedes developed an approach using circumscribed and inscribed polygons to prove that the value of pi to be between (223/71) < π < (22/7) (3.1408 < π < 3.1429). This geometrical approach was predominantly used by mathematicians for the next 1000 years, were in 1630 an exact value of π was found to 39 decimal palaces.
Sometime around the year 1425, a new approach
Pi is an irrational number that represents the ratio of a circle’s circumference to its diameter. In the Mile of Pi, Numberphile printed out the first million digits of Pi in a continuous long piece of paper, which stretched for over a mile. They printed out pi and rolled it out for one mile to show that there are cycles of repeating sequences within pi and that every number does not appear evenly. Brady Haran also presents some interesting things that could be found along the way. He points out the Feynman Point which has the number 9 repeated six times. He also pointed out the point where Akira Haraguchi (known for memorizing the most digits of pi) memorized up to. When they reached the end of the mile long paper, the last digit was 1 in
Now that we have the history of Pi out of the way, I bet you're intrigued on how people use Pi on an everyday basis . Pi is mostly used In circumference also known as perimeter . There is diameter and radius, diameter is solved by doing ‘3.14 * 12’ while radius is solved by ‘2*3.14*6’ squared . In case you didn’t know, diameter is the whole thing while radius is just half, which is why i used the example of twelve and six. Pi is also used in people’s everyday life , such as scientist when they search for new planets outside of our solar system .
Since elementary school, I have had a joy with memorization and numbers, and eventually I discovered pi, the infinite-lasting ratio between the circumference and diameter of a perfect circle. In this paper I explain why I like pi, how much of pi I have learnt, and the story of my science fair project. Pi has also been a large reason of why I enjoy math and school in general.
At the beginning of the book, Pi is a religious teenager, a vegan, and a relatively humble person. Pi belongs to three religions and is a very religious and believing person. It is his willingness to believe and
Pi is a boy who was born and raised in India. He was born to a Hindu mother who taught him Hindu beliefs throughout his life. As he got older he also came to be a christian and a muslim. Pi lived
Pythagoras developed the formula a2+b2=c2which is called the Pythagorean Theorem. They formula helps find the measure of the sides of a right triangle and is still used on a day to day basis in order for society to function. Overall, mathematics developed by the Greeks have been very useful to modern
Dinostratus was known for using the quadratic to solve the problem of squaring the circle. He created a formula of the trisectrix of Hippias, which allowed him to find the squaring the circle. Due to this accomplishment he was now known for the quadratic of Dinostratus. However , Dinostratus did find the solution for the problem squaring the circle, but he did not only use the ruler and the compass alone, the mathematician knew that the solutions violated the foundational principles of their mathematics. In like two thousand years later it was proved impossible to use the ruler and the compass
Additionally, more often than not in many equations, the number 2 precedes π: the value of tau. It would prove to be less ambiguous and fundamentally sound to replace 2π with τ. One of its advantages proves to be the benefit of a clearer understanding of arriving at π, which essentially skips the step and simplifies without explanation. However, as many pi supporters point out, tau is not the simplest form in many cases. As Matt explains in the “Tau vs. Pi Smack Down,” pi is a much cleaner and simpler unit to use in explaining the angles of
I have discovered that Pi and I have some differences and some similarities. I found that we also have a lot in common and a lot of the same problems. I found all this out while reading the book and watching the movie.

He had many discoveries that contributed greatly to the mathematical community as well as to the world. Most of his mathematical contributions were in the area of Geometry, but he had many contributions in Algebra and Science as well. He was fascinated with geometry and spent much time drawing out geometrical figures and formulating proofs and theorems. Archimedes determined the exact value of π. he obtained this by circumscribing and inscribing a circle with regular polygons having 96 sides. he also discovered the relation between the surface and volume of a sphere and its circumscribing cylinder.
The nine chapters on the mathematical art is an anonymous work, and its origins are not clear. (Jing Fang,Liu Xin, and Zhang Heng, People guess one of these three people is the author of book.). Yet it is only one Chinese mathematics book in Zu’s age. Zu have studied mathematical in this book and use it’s equations and theorems to calculated Pi, sphere’s equation, completed Daming calender, and other mathematical or astronomy works. Shuishu(The Method of Interpolation) is a mathematics book by Zu Chongzhi and Zu Geng(Zu Chongzhi ’s son). This book become math textbook at the Tang dynasty and it also revised problem of The Nine Chapters on the Mathematical Art. This book also recorded Zu’s equation to calculated Pi and area of sphere, but it is lost in Song’s dynasty(The period after Tang’s dynasty).Therefore, Nobody know how Zu calculate the Pi and the area of sphere.Historians believe if Shuishu is survived,the history of Pi will be change and we can have another way to calculate corrected value of Pi. Historians also guess Zu Chongzhi knows that “if a/b ≤ c/d then a/b ≤
The quadratic formula that we know today was published by Rene Descartes in La Geometrie in 1637.
The concept of pi has been known to humans for centuries. Its relationship with circles meant early civilizations also had ideas about the number P (Crilly, 2007). The
Who created it, you may be open to know that Pythagoras was the one invented the Circle of Fourths and Fifths. Pythagoras was
