Pi is represented by the Greek letter (pronounced pài) and is a constant (approximately equal to, representing the ratio of the circumference to the diameter of a circle. It is an irrational number, i.e., an infinite non-cyclic decimal. In daily life, it is common to approximate the approximate rate of pi.

Characteristics of pi:It doesn't really make much sense to calculate the value of pi so precisely. The value of pi used in the field of modern science and technology, a dozen digits is sufficient.

If the size of the observable universe is calculated with a 39-bit precision pi value, the error is less than the volume of an atom.

In the past, people calculated pi to ** whether pi is a cyclic decimal. The mystery of pi has been unveiled since Lambert proved that pi is an irrational number in 1761 and Lindemann in 1882 to prove that pi is a transcendent number. It plays a very important role in many areas of mathematics.

Pi is represented by the Greek letter (pronounced pài), which represents the ratio of the circumference to the diameter of a circle. It is an irrational number, i.e., an infinite non-cyclic decimal.

It is also equal to the ratio of the area of the circle to the square of the radius. It is the key value to accurately calculate the geometric shape of the circumference, area of the circle, and the volume of the sphere. In analytics, it can be strictly defined as the smallest positive real number x satisfying sin x = 0.

The origin of the introduction:

It originated from the Greek word peripheria, which means edge, border. Although it has been used in the four ancient civilizations for a long time, it is still back to the 17th century that it was really defined as a universal constant.

In 1748, the mathematician Euler really brought it into the understanding of mathematics by defining and using it in his book Introduction to Infinitesimal Analysis. Probably because of the simplicity of the definition and the ubiquity of mathematical formulas, it appears much more frequently and prominently in popular culture than other mathematical constants.

If you are satisfied, please light up the five little stars, your evaluation is the best encouragement to me, I wish you a happy life!

Sincerely answer every question for you!

Let's learn from each other and progress together!

Thanks again!!

Pi is represented by the Greek letter (pronounced pài) and is a constant (approximately equal to, representing the ratio of the circumference to the diameter of a circle. It is an irrational number, i.e., an infinite non-cyclic decimal.

In daily life, it is common to approximate the approximate rate of pi. Ten decimal places is sufficient for general calculations. Even the most sophisticated calculations for engineers or physicists can be taken to a few hundred decimal places.

International Pi Day

In 2011, the International Mathematical Association officially announced that March 14 of each year will be set as the International Mathematics Festival, ** which is the pi of the ancient Chinese mathematician Zu Chongzhi.

International Pi Day dates back to March 14, 1988, when Larry Shaw, a physicist at the San Francisco Museum of Science, organized museum staff and participants to make 3 and 1 7 circles (one of the approximations of 22 7) around the museum's monument and eat fruit pie together. Since then, the San Francisco Museum of Science has continued this tradition by hosting a celebration on this day every year.

In 2009, the U.S. House of Representatives formally passed a non-binding resolution setting March 14 as "Pi Day" every year. "Given that mathematics and the natural sciences are an interesting and indispensable part of education, learning about them is a fascinating way to teach children geometry and engage them in the natural sciences and mathematics......It is approximately equal to, therefore, March 14 is the most suitable day to commemorate Pi Day. ”

The last 50 digits of pi are.

The 50 decimal places are: 26535 89793 23846 26433 83279 50288 41971 69399 3751

Pi is an infinite non-cyclic decimal number: 592 653 589 793 238 462 ......So the 20 decimal places are 141,592,653,589,793,238,46

Come on, pose well, and read it in one go.

Pi is represented by the Greek letter (pronounced pài) and is a constant (approximately equal to, representing the ratio of the circumference to the diameter of a circle. It is an irrational number, i.e., an infinite non-cyclic decimal. In daily life, it is common to approximate the approximate rate of pi.

In 1965, the British mathematician John Wallis published a mathematical treatise in which he derived a formula that found that pi is equal to the product of the multiplication of infinite fractions. In 2015, scientists at the University of Rochester discovered the same formula for pi in quantum mechanical calculations of the energy levels of hydrogen atoms.
