Find pi 21 decimal places 50 digits

Let's imagine a drunkard drinking in a mountain temple and getting drunk to death in a ravine

A pot of wine in a temple on the top of the mountain (, children's music (26), I don't have enough three pots to eat.

535897), the wine was spilled (932)! Flash immortal (384), walked (626), died mountain fan fan (43383), child abandoned ditch (279). [Top 30].

Then imagine how the father of the "deceased" would feel when he learned that his son was "dead":

My Pain (502), it is sad enough to die in vain (8841971), leaving it to the ravines and ravines.

69399）。[15-bit].

Imagine the scene of the father of the "deceased" going to the ravine to look for his son:

I have back pain (37510), I'm afraid that you will freeze for a long time (58209), and I will think about it for a long time.

74944）。[15-bit].

Then it was the father who found his son in the ravine and brought him back to life. The son has found his way back.

Scenario: I save my child (592), turn into a cave (307), and don't stay (816). Neighbor Le (406, child unhappy (286), child hurts dad for a long time (20899). Dad Leer doesn't understand (86280

Think twice (348)! 'Enlightenment (25). Think twice and follow (34211), and wait for a long time (70679) [last 40].

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

Circumferential hand base rate.

Accurate to 20 decimal places is yes or yes. Bicha Jin.

The top twenty positions in pi are:

Pi this thing to take the jujube seems simple, but when you go to memorize it, you find that it is actually difficult, I have also brain-pumped back, two hundred a week, at the beginning are simple, but when you memorize to 100 to chain sensitive liquid after not think so, when a hundred shed after the level of normal people can not memorize, rote words may have forgotten the front, I memorize a number of numbers slowly memorized, skilled to no, closed eyes do not need to want to blurt out directly, but in fact, this thing is useless, Professional direct calculator, in reality want to pretend to be 13 but no one listens, annoying (I recited two hundred to my friend, just half of the recital, he gave me a big mouth, said, "Are you okay?") "I'm really convinced.

To sum up, pi is really not worth memorizing, but it is also a good way to have time to memorize and connect with memory.

1000 decimal places.

Formula. As we all know, pi is a well-known irrational number, an infinite non-cyclic decimal number, irrational numbers are not easy to remember, if you use the "homophony method", the first 100 decimal places are compiled into the following smooth mouth, it will not take a few minutes to remember. First of all, imagine the process of a drunkard who is greedy for a cup of wine and drinks in a mountain temple and gets drunk and "dies" in a ravine (30 people).

26 535897 932 384 A pot of wine in a temple on the top of a mountain. Children's music: "I don't have enough to eat in three pots".

Wine kills", can't kill, 626 43383 279 Happy and happy, die three three bars three, give up wine. Then imagine the thoughts of the father of the "deceased" when he learned about it (15): 502 8841971 69399 My son:

It's sad enough to die in vain, and it's left to the ravines and ravines." Imagine the scene of the father of the "deceased" going to the ravine to look for his son again and again (15): 37510 58209 74944 I have low back pain in the mountain, I am afraid that you will freeze for a long time, and I will think about it for a long time.

Imagine the scene of finding the "dead" in a cave and reviving him (40): 592 307 816 406 286 20899 I save my son, the cave is turned, and it is not appropriate to stay. The neighbors are happy, the children are unhappy, and the children have been hurting their fathers for a long time.

86280 348 25 34211 70679 Dad Le'er doesn't understand, "Think twice!" "Enlightenment, think twice and follow, and your wife will be happy for a long time. The above slipping away is inevitably a bit of a patchwork, the bull's head is not the horse's mouth, but it visualizes the abstract number string, which is very conducive to memory.

It is an irrational number, i.e. an infinite non-cyclic decimal.

Precise to 20 digits are, , pure hail sedan 26535, 89793, 23846. Because the 21st digit is to do 2, it is rounded to the 20th digit and the 20th digit is left to 6.

Pi is accurate to 20 decimal places. It is a non-cyclic decimal.

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.
