    I am an American engineer and I just watched this playlist to review some concepts. what I realized is that the American education system is seriously flawed and almost completely failed me. I even went to a private school where i completed first year calculus and yet somehow had to wait until college before I ever saw an argand diagram or a vector. some people here are even seriously trying remove algebra as a requirement to get graduation rates up. mr. woo, you are an amazing teacher and I am on to your logarithm playlist to see how else my expensive private American education failed me.

      I agree. I was lucky; my Dad was good at Algebra and Trigonometry so I caught a break. He tutored me and my friend, showed us how to find the square root of a number, by hand; he thought it ABSURD that American schools didn't teach us something so simple.But not everyone has Family or Friends knowledgeable, in Math particularly. That's when you have to rely on the school teachers & Education system and we didn't have youtube with awesome teachers like this guy, Sal Khan, Pat JMT, guy from 3Blue1Brown, Bill Shillito, etc. I graduated high school in '97, worked towards an associates in Music and CAD Design. Now I am going back for Logic/(Math.)

      Brett Cooper Wow the uk education system is better than I thought then, how can you possibly get onto an engineering degree without seeing a vector or knowing logarithms like the back of your hand. Even standard A level maths (16-17 year olds) in the U.K. has 3D vectors in. That's without choosing further maths, also did you do physics? If so surly they taught you what a vector was

    You’re an excellent teacher. I’m continuing to find myself even more lucky, as these concepts just make sense in my head. I just watched your calculus part 1 and 2 videos and it doesn’t seem nearly as hellish as many of the people I know describe it to be. I haven’t felt challenged much at all all the way through pre-calc. I plan on taking calculus my senior year of high school and I’m beyond excited. Hopefully I’ll actually have to put more thought into what I’m doing. I love math; I always have and always will. Not many people do, but I know that teachers like you give a sense of hope and understanding to people who don’t like math, something I fortunately have always had that I consider to be a gift.

    Arabic numbers like we use today are slightly modified figures that show corners you can count. For example the 2 looked like a Z and it has 2 corners.

    Al-Gaber "الجبر" is an ancient Arabic word that roughly translated to "inference from hidden truth" which came from the Islamic scholars who invented it and understood the principle connections between groups of numbers in a "formula".
    What's also interesting to note is that Algorithm comes from the Latinization of the Persian scholar Al-Khawazimi who pioneered the mathematical concepts that lay the foundations for the Turing test.

In germany its just a teacher asking and asking a LOT of irrelevant questions to us which basically makes our grades. You are telling so much information and the students just answer what they think so that you can comment on that. Until that video i did not even know that the Z stands for Zahl. (I think you said it means counting but actually it means number. not sure if you really said that) I love your vids! Keep going!

    one correction: the "anglo" numbers used don't count the lines, they count the angles. which is why the number 1 has a short line ticked on the main line. these originally were Arabic number script which Europe transitioned into during the renessance period, while Arabs steadily moved to use Indian number scripts, as they dove into the concept of zero from the ancient texts of Indian scholars centuries ago when trade routes were established at the end of the Islamic Empire's conquest age.

  • @davidshechtman4746
    @davidshechtman4746 2 ปีที่แล้ว +1

    So the principal square root of 4 is two. But we recognize that there are actually two possibilities, two or negative two. Clearly the relationship going backwards from the creative process of geometric combination is not functional in terms of passing a vertical line test. In the case of (rectangles and squares drawn in the second and fourth quadrant) negative four we have either 2 × -2 or -2 × 2. There is no reason for imagined numbers. There are no inconsistencies in the recognition of alternately signed numbers being possible factors in the geometric composition of binomially factorable rectangles. The complex plane has been fruitful certainly. But the simplest way to analyze factors of squares is to be consistent with the Cartesian model.

  • @nas8318
    @nas8318 4 หลายเดือนก่อน

    This video starts by going to the "beginning of numbers", and by that the teacher means Roman numbers. Numbers were created in modern day Iraq (Akkad, Babylon) thousands of years before the Roman empire. The teacher then calls Arabic numerals "our numbers".
    This bias is unfortunately common in the Western world and results in an effective embargo of credit on the Middle East and the Arab world. Stories always start with Greece or Rome, we're happy to occasionally credit China or Japan, but when it comes to the Middle East and the Arab world, we do our best to avoid crediting it altogether, and if we really have to, we either use vague terms (West Asia) or Greek terms (Mesopotamia, Philadelphia etc...) to obfuscate any link with the region.

  • @andrewgonzalez7143
    @andrewgonzalez7143 7 ปีที่แล้ว +13

    Actually the Arabic numerals reflect their own values based upon how many non-obtuse angles are needed to write the numeral, NOT how many straight lines there are. Look up the first writings of Arabic numerals, and you'll see plenty of diagrams that show this.

    • @janglestick
      @janglestick 6 ปีที่แล้ว +1

      no its not exactly a myth, it's just that as you go higher in quantity different systems contributed and were absorbed. You can find many versions of the number 9, some of which attempt to make the system work. The symbology changes. For example, the number 7 with the line drawn through the middle (which isnt in the txt char) is essentially the center of the number 4 with a triangle on top, 4 + 3. There are some very peculiar versions of 9, almost all had the same middle dash as the 7, and most had many more little dashes added. It seems to follow the same set of 'rules' as the 5 and 6. Another way to see the system is that you are confirming the tokens in a trade. Someone places tokens / coins on the ground, and you draw a line around them, confirming the tally, using the shape of the numeral.

    Is there a reason that Quaternions don't feature in the Fundamentals?
    Is it just that they don't resolve a contradiction or inconsistency in the prior art?
    If so, how do we know that we have all of the fundamental operations. After all, one could say that addition and it's inverse, subtraction, implied the negatives - and then stop, calling number theory complete.
    When we added multiplication, its inverse implied the reals. But again, we could have stopped there and called it complete.
    So, do Quaternions truly not belong in the evolution of number? Is there an operation we're not considering which implies them?

    1. Have Numbers been created/invented by Man. I think so.
    2. Are Mathematics created / invented by Man or Mathematics were / are discover able ? Personally, I think that Mathematics were / are discover able.
    2. This debate has brought God into it ! Did God created Mathematics ? Obviously, no one could prove the existence of God, but it is only a belief because Humans are not use to Things falling from Nothing. So, the belief that God created all Things.
    What is of immediate interest is my Question in 1. above. Are Mathematics created / invented by Man or Mathematics were discovered by Man ?
    Thank you.

      Mathematics is discovered and tricks are invented by human. Let consider the circle, it exists in nature before we human find its credentials and equations where you can solve the equation in more than one way is the trick to tackle the problem. We humans just take-off the dust from the hidden truths. as much i understand.

    If you really want to understand real, imaginary, and complex numbers, as an electrical science teacher, NOT a maths teacher.

    "Zahl" means "number", not "counting"

    Yea, however complex numbers only "work" because fundamentally they rest upon and boil down to the absurdity and contradictory : -1 = 1 and that is utter twaddle.

    why you don't say that 1/2 is a real number, you are choose it as rational, i know that rational number is real number as well...

    if something is complex... it should be left alone.. in oblivion
