    I watched 4 videos _"explaining" Pi before coming across yours.
    None of them helped, and they were all ridiculously long, filled with a bunch of people wanting to hear their own voice.
    But then I saw *your* video.
    *I now understand pi*.
    Thanks!!

    Took me 12 years in school with math, and I find the concept of Pi in a freaking youtube video.. Pathetic school system we have! Anyway, thank you for making me somewhat more educated after the destruction from public school! :)

      Oh god, man... I can totally relate. Came here after finally realizing the concepts of volume and area on my own. Couldnt figure out Pi.
      Why aren't we taught this shit in school? It's waaaay better than having kids blindly memorize meaningless formulas. This makes them think (but Im sure you already knows that, haha.)

      QuidQuoPro You’re right for the majority of the school system, but the system lets teachers bend the rules a bit so the students can understand. For example , some teachers like my teacher, Mr. Heine, legit makes us understand why fractions are fractions, algebra is algebra and don’t even get me started on geography. I agree with you for the majority of what you’re saying, unless you have that 1 teacher. Wait... why don’t you just ask the teacher after school is over? That’s what I do.

    I'm just here to say thank. When I was a kid, my teachers never explained to me what was exactly PI. Everybody knew PI=3.14 without knowing what PI was. We just knew it was just part of a formula. I went to college and utilized PI zillion of times. For some weird reason, today the perimeter formula C=2PIr pops up to my head. I got curious then realized that I only knew the value of PI without knowing what it was. It took me forty years to find out. Thank you!

  • @learnmathtutorials
    @learnmathtutorials  12 ปีที่แล้ว +2

    The symbol pi represents a number that has an exact value (the amount of times the diameter of a circle wraps around its circumference) However, if we try to represent this exact value in terms of a number, the digits of the number go on forever.
    We can not show an exact value for pi by representing it as 3.14159..... so instead we give this number the symbol "pi" to represent it's exact value.

    Ok this is what I cannot figure out, so I am asking for help:
    The circumference of a circle is found by multiplying the circle's diameter (which is a finite length) by Pi (which is irrational because there is not a final number beyond Pi's decimal point).
    So with that in mind, this is what I can't figure out:
    Let's imagine we have a circle with a diameter of 1 unit of length.
    That would mean that the circle's circumference (which is finite in length) would exactly equal the value of the constant Pi, which goes on infinitely!
    How can a finite length equal exactly, the value of a number that goes on for infinity??
    Help!!!

Where as in your explanation you showed us a tiny part where the diameter wont fold completely for the fourth time. Which means its a tiny place having a starting & ending point. Which clearly states that the decimal part of the pi can end. ! Explain the decimal part please & how far it go & if we can figure it out manually with calculations.

    Um guys, this was simple just put in on the formula. It's not like school didn't teach this to us, we just didn't realize. Circumference=π×diameter so π = circumference÷diameter and dividing by diameter just means to divide the circumference into equal parts using diameter as a divider.

    So it’s how many radians cover a circle or how many arc lengths cover a circle ?

    my pi mystery solved.
    I was sooo confused if pi was 22/7, its clearly rational and its value came 3.142857142857... which repeated so it was rational. THANKS A LOT AND YOU DESERVE A SUB AND A LIKE :)

    Yes! Yes! Yes! You really simplified it. I'm serious, i never heard anybody break it down like that. I always thought Pi. Was on some waaay HIGHER-LERNING shit!!! But, its as easy as " A-B-C " Dig It???

    So, since the school of I guess everything starts from Greek as the only arithmosophic (words have mathematical properties e.g the word son has the same sum with father etc) language what we need to change is π (pi) because pi comes from the word περιφέρεια (periphery) but what mathematically pi is the constant ratio 3.14... of diameter to the periphery logos and the Greek word for the diameter is DIAMETROS (Διάμετρος=meaning through the centre of the all) so the letter Δ (Δέλτα) is the appropriate letter for 3.14... Also the Greeks had and a have a poem that helps to memorize 3.14... first hundred letters and what is fascinating is what the poem says. For your entertainment, I quote the first verse: "AEI O ΘΕΟΣ Ο ΜΕΓΑΣ ΓΕΩΜΕΤΡΕΙ". Now, if you count the letters of every separately you have π(pi). Here we go AEI=3 O=1 ΘΕΟΣ=4 Ο=1 ΜΕΓΑΣ=5 ΓΕΩΜΕΤΡΕΙ=9 }=314159 and remember this is 2500 years old quote. If you are still here let me tell you one last thing. What does the first verse of the poem "AEI O ΘΕΟΣ Ο ΜΕΓΑΣ ΓΕΩΜΕΤΡΕΙ" means? Well, it says exactly this: ETERNALLY THE GREAT GOD GEOMETRIZES!

    A much better explanation is to just say that all circles have the same proportions no matter how big or small they are. So the diameter and circumference will always have the same proportion no matter the size of the circle. And the proportion of circumference to diameter is always 3.14

  • @AbhiBass96
    @AbhiBass96 6 ปีที่แล้ว

    The diameter can be any number (nth) and we would still need 3.141.... of the diameters to fit the circle...?
