      And yet I throw away my valuable time in school when I can simply learn without pressure from books and the internet. But no, monopolies hold so much influence over the education system, changing the education system would be the equivalent of those monopolies loosing millions. I guess I have to force myself to "learn" in a monotonous curriculum that was designed by the school district in order for me to regurgitate information and throw it up on a test.

      yeah i never got where that area business came from. i just accepted it and memorised the rules. and got done with it. i knew the area was used to discover some integrals. like 1/x well if we used the 1/alpha rule we´d get 1/0*1 (as x to the zeroth power would be 1) and that is utter nonsense first it would be a constant no function second it´s literal physical pain for everyone with a bit (even my mini mini mini bit) of mathematical understanding. 1/0 that hurts. does that mean yo ucan´t integrate it? looks like it right? but i think Leibniz (might be wrong here though) found that the Area under the curve grew logarithmically. setting up the real butt saver S 1/x dx=lnx . but i always just accepted "okay the integral is magically bound to the Area under the curve".

    I love that the gradient of the area rectangles animated the idea of smoothness. When there are 8 large rectangles, each rectangle's color is noticeably different from the color of the adjacent rectangle. As the rectangles get smaller (approaching the area under the curve) the colors approach a smooth gradient as well.
    It seems that beautiful and subtle tricks are your forté, and this one is no exception. Thank you for your very helpful videos!

      @@rikitobruece2386 I hope I can aid to your understanding, although it's been 2 weeks since you posted.
      You can imagine the integral to be the "sum" of all the tiny strips that an area under the curve has been broken down into. The caveat is that you must remember that the integral is not just the sum of all area strips, it is the sum of the strips as these strips approach zero width. That's why integral is different than the ordinary sum.
      Why is it opposite to the derivative?
      Let's say you have the information on the distance travelled by a car with respect to time,and you want to find the velocity of the car during that time interval. You would use the derivative of that distance versus time function.
      Now reverse the situation. Suppose it so happens that you have absolutely no data about the distance your car has travelled, but you just have access to the speedometer(i.e. velocity). You intend to find the distance travelled by your car through this data of velocity versus time. Earlier, you had distance versus time and you found velocity by taking the derivative. Now, when you have velocity versus time, and you want to find the distance, you would take the "integral" of the velocity data.
      So in these two situations, you seek to find the derivative of a given function, and in the next situation, you already have the "derivative"(in the form of velocity data from speedometer), and you need to find the function which has this derivative(distance). This is called integral.

    This series on calculus was my first introduction to the subject when I was exploring it for myself before learning it in school, so when I came to studying it, I actually had an idea of how to solve different and interesting problems because these videos taught me why they work and more generally the theory of the subject, rather than blindly applying high school formuals to solve homework and exam problems. This series in particular is what first truly lit up my love for mathematics, and I cannot thank this series and channel enough. This is what schools need: giving children the ability to be understand why the maths works, and I believe it would really make more students grow a love for the subject, as it is not just memorisation, but derivable logic.

    When you compute a definite integral - an integral between two values - the constants cancel out, so in this case we can ignore it (and could have ignored it even if we started at _t_ = 2). However, it becomes important when taking the indefinite integral, so I'm glad you mentioned it.

    @johannmeier6707 Год назад +3

    What I missed when you explained the substraction of the upper minus the lower bound was the graphial meaning. What you actually get when inserting any(!) bound is the whole area from 0 to this point. If you want not the whole area beause the area starts right of the center, you just have to substract the area up until this point. This happens to cancel out the constant, yes, but "full area minus not wanted area = wanted area" is a more intuitive reason as to why to substract upper minus lower bound. There's nothing special about the lower bound as it also just gives the area from 0 to this point, just as the upper bound does.

      No it doesn’t, that’s what’s so neat about it! Such an elegant solution to a apparently complex problem. First you’ve got to find your range for which you want to compute your area, then you invert that range and then multiply it by the integral of the range in question. This will give you the average value of velocity.

    • @MrMineHeads.

    • @mrmabb123
      @mrmabb123 6 лет назад +2

      Just to clarify: by v(t)= t(8-t) is an example. It means that t(8-t) is just a function to describe the curve in the graph. v(t) can be v(t) = t^2 + 8t+8 or v(t) = t^4 + 8t^2+t but the curve would change accordingly. So this velocity function is a function and not a formula of velocity(v=s/t).

    • @roger1561
      @roger1561 4 года назад

      Indeed, that simple "t(8-t)" had me stuck in the mud until could figure a workable explanation. Namely, 3blue1brown needed the simplest function to demo the anti-derivative, do he chose a perfectlly smooth start-accell-decell-stop function that could EASILY be anti-derived from t(8-t) [or "8t-t^2"] to "4t^2 - t^3/3" . The simplest derivative he chose to start with was t(8-1) where "8" is the 8 seconds shown on the x-axis. Now, the distance travelled at each time unit 1 thru 8 EASILY computes using t(8-t) to 7,12,15,16,15,12,7, 0 meters. Hope this helps.
