The Best Explanation of Pi 

រឯថង

@@SaDa-jk7xq I like your funny words magic man

Thank you.

Inaccurate is reasonable? And we wonder why we don't have a complete model of the universe. We can't even figure out circles but I guess everyone seems satisfied with being a little off. What does it matter if we are 10^-100 off?.... right? Or perhaps using the relationship between a straight line and a curved line is like comparing apples to oranges. There has to be a better way. A circle is completely enclosed. It's finite but pi is not. Our language of mathematics is fundamentally flawed. We need a new language that goes beyond calculus. One that is more truly accurate. And doesn't have ANY error.

@@duckyoutube6318or maybe we just cant understand irrational numbers fully?

holy shiet 1 minute video worth more than 12 years of school 😭🙏

maybe they didn't understand you because of your english

English is not seince

Math sucks pick a better subject to teach!

@@domgena uh no actually math is the only important subject that exists in every country so duh 🤦‍♂️

@@NovaStrike118 there's nothing wrong with the sentence...

that is stupid

Thank you Ima try that to get more clarity

vaibhav patil discovered

+JoePro Cast yeah i agree

+vaibhav patil ..... PI was invented with a very big Circle to make the equation an everlasting oo infinity. There is an actual equation for PI. LOL

+vaibhav patil We invented the method of mathematics that allows us to discover Pi

Mathematics is a human invention, and it is not absolute knowledge: there is no such a thing as existing formal concepts of mathematics as phenomena, such as the sun, a dog, a human or an ant. Concepts do not exist, they just subsist in their thinking ontological frame of principles and intuition.

But why can't it be exact instead of just 3.14, but 3.14159 . . . . ad infinitum? Because we're comparing a straight line (diameter) to a curved surface?

@@Unfamous_Buddha Yes its strange to me that the numbers go on forever. Why is pi irrational? Is the circumference irrational too?

xxuncexx Archimedes made a brilliant way of calculating pi. He didn't measure it at all, he calculated it, and you can use his method to get as many decimals as you want. I think that it was genius, make sure you take a look at it! 😊

Yes he did. You can imply a calculation from the explanation. Circumference = Pi . Diameter (there in his example D =1) Therefore: Pi = Circumference / Diameter You can also calculate PI if you measure the are of the circle. Area = Pi . Radius^2 Pi = Area / Radius is ^2 Also, if you differentiate the A = Pi.R^2 formula, you get 2.Pi.R ... where 2R = D which is the circumference. Also, if you integrate the c = Pi.D formula (2.Pi.R) , you get 2.Pi.R ^2 / 2 or Pi.R^2, which is the area.

@@paulg687 I think ops point is that in the case of Pi = Circumference / Diameter or Pi = Area / Radius is ^2 both circumference and area are difficult to find without the use of Pi in the first place. If you don't know either Pi, the area of a given circle, or the Circumference of a given circle flipping these equations around doesn't help.

@@cavycorp9136 if you measure the circumference and the diameter and find their ratio you’ll get a number. Try this for ANY circle, this will be the same. It’s therefore a constant. More importantly though , it’s a natural number for the circle since it can be done for all circles. That’s all there is to it. You can then deduce a formula which includes this constant. Btw, you shouldn’t get hung up about the Greek symbol itself. Just use 3.14 if it looks strange to use. PI, or any Greek letters, are used like this to represent a long number. Easier to write. So you wrote pi instead of 3.141592657…. It’s also the same deal with the ‘e’ in continuous compounding. People shy off when they see it. That too is just a number of 2.7183. This one is the natural number for continuous compounding. You can use the number instead of ‘e’.

If you know basics of trignometry, you can study finding of pie from archimedes method, if you know binomial expansion and calculus, you can study method of newton.Till now, several ways of finding pie are devised

Stop with that nonsense. Who are these Greeks? Read unbiased ancient history There were no Greeks.

Yeah, irrational numbers are simply not meant to be converted into fractions because they cannot be.

@@pratijitpodder4345 But they can be approximated to any degree of precision by a fraction (i.e., rational number). Fred

Amiga never gets old! 🙂

it is irrational not repeating. And, in reality, you can't measure ANYTHING with zero uncertainty.

I know that this comment is 12yo, but actually, this video doesn't prove that this is constant, it just provides visual intuition what pi is in relation to diameter. Calculating the numerical value of pi can be done through many (infinite!) ways, and most of them are using very complicated power series that don't make much sense intuitively!

Proof it dumbo

Also I believe pi is means to signify forward progression in the the development of our subconscious which in turn molds our personality, our heart, so we eventually use the parts of our brain that are trigger by impulse , emotion and intellectual thought so in time through repetition become a single intellectual engrained heartfelt response , 3 to 1. Pi in nature is good luck. I feel it’s God reminding to stay righteous and upright no matter the size of the storm. God is always there present whether you believe or not. God is life and the interactions of life and love is the appreciation of life and the interactions of life. God is the epitome of good. God is an all encompassing spirit and not a sinner.

I'm sorry, but there seems to be a misunderstanding in your question. A circle does not have a finite number associated with it in the same way that a numerical value or quantity is associated with a finite number. A circle is a geometric shape defined by a set of points equidistant from a fixed point called the center. It is a two-dimensional object with no edges or corners. The properties of a circle, such as its circumference, area, radius, and diameter, can be expressed as numerical values, but the circle itself is not inherently associated with a finite number. For example, the circumference and area of a circle can be calculated using numerical formulas, but the circle itself is not a numerical value. Its properties depend on the measurements (such as radius or diameter) assigned to it.

Holy crap, I was just about to make the same comment! You can take a string of arbitrary , finite length and form a 2D circle with it.

Where u get it the circumference is finite???

A circle is a polygon with an infinite number of sides. I think that is where the answer lies.

@voidphoenix9024 Not every number of the form p/q is rational. p and q are supposed to be integers (we can have q to be only a positive integer since we can obtain negative sign from p)

Aren’t you just saying that if you sum it the value of each digit in pi it tends towards a total of… pi? 🤔

why not

We concern us with pie to understand how to calculate things like a dam for water, etc. That you may know. The goal to achieve accuracy for pie, in my opinion, has more to do with achieving mathematical prove and certainty and to find completeness. Any other possibility must either be prove as complete, or dismiss as not satisfying such prove, or exclude any other prove that may or may not have relevance to the completeness of what needs to be proven. For every digit added to pie, our desire to achieve completeness by prove is satisfied and our suspicion that the prove for completeness does indeed exist is solidify for the benefit of future generations. Mathematicians needs prove, so does Scientists and Biologists for their respective field of study. Unknowns must either be prove or disprove. Careful elimination is needed, and mistakes can have disastrous consequences. Why does a gap exist when a diameter is fitted around the circumference, leaving us with 3.14...(excluding other possibilities) The circumference is complete, but the diameter causes a calculated shortcoming. Should it be like this or shouldn't it? No matter what logical explanation is giving, it appears from prove that the gap is infinite, and that the prove that the gap can be complete is elusive in its make up, hence the prove for the next digit(s)Until then, the next digits will remain like this, dot,dot, dot....

​@frankwewers58dot dot19

Just knowing lol 😅 how u know right and wrong ??

I assume it would have originally been derived by physically measuring circular objects, such as putting thread around a wheel.

let's say I'm not at all a math professor of any kind, I'm just using common sense and logic thinking

Supercomputers use formulas that don't require a circuference or diameter.

Rounding. It’s an approximation.

@@MuzixMaker fair enough, maths is so flawed though, can't even make divide 10 or 100 or 1000 by 3 properly

thanks

Glad it helped you

Idk what your age have to do with anything
