Pi 100 full version The jingle is a pot of wine in a temple on the top of the mountain. You can eat the wine and kill it, but it won't kill you. Die Shanshan, take a second wife. Not only my wife, but also my uncle and my third wife saved my shine. I cheated on my dad, my uncle (actually pulling my uncle's ear) and my wife. Don't slip, commander. Don't slip. Hold dad for a long time. I will die if I am hungry. I am really hungry. I want to eat human flesh and lollipops.
Pi is the ratio of circumference to diameter. Its calculation has always been a very interesting problem for mathematicians at home and abroad. A mathematician in Germany once said that the accuracy of a country's calculation of pi in history can be used as a sign to measure the mathematical development of this country at that time.
Characteristics of pi:
It is of little practical significance to calculate the value of pi so accurately. A dozen pi values used in modern science and technology are enough. If the Hubble volume is calculated by using the 39-bit precision pi value, the error is less than the volume of an atom.
In the past, people calculated pi to explore whether pi circulated decimals. Since Lambert proved that pi is irrational in 176 1 year and Lin Deman proved that pi is transcendental in 1882, the mystery of pi has been uncovered, and pi plays a very important role in many mathematical fields.
Extended data:
In ancient China, the calculation of pi was ahead of the world level for a long time, which should be attributed to the new method "pi" founded by Liu Hui, a mathematician in Wei and Jin Dynasties. The so-called "tangent circle method" is a method to calculate pi by using the circumference of the inscribed circle of a regular polygon to approach the circumference infinitely. This method is a brand-new method created by Liu Hui after criticizing and summarizing various old calculation methods in the history of mathematics.
Pi is expressed by the Greek letter 7 1 (pronounced pai), which is a constant (approximately equal to 3. 14 1592654), indicating the ratio of circumference to diameter. It is an irrational number, that is, an infinite cycle decimal.
In daily life, pi is usually expressed as 3. 14, which is used for approximate calculation. The fractional part 3. 14 1592654 is enough for general calculation. Even if engineers or physicists want to make more accurate calculations, they only need to take the values to a few hundred decimal places at best.
