Clarification: At 8:32, I state that the antiderivative of e^x is e^x. This is not entirely all-encompassing. The correct form of the antiderivative of e^x is f(x) = e^x +C, where C is any constant, like 0, 2, or -12.56. This is because the derivative of e^x +C is e^x (the constant term always vanishes in a derivative). However, I wanted to demonstrate in the video that e^x is its own derivative and antiderivative. Furthermore, when we look at the area under the curve of e^x, it is only equal to e^x. This is the point I wanted to demonstrate when integrating e^x.

8:32 where is +c?
@pentagon-math2 күн бұрын
You bring up a good point. Generally, the answer to an integral should have a +C, but the point I was trying to demonstrate was that e^x is its own derivative and can be its own antiderivative. In the video, we are primarily interested with the area under the curve, which is e^x. However, it is true that the derivative of the function of the form e^x +C is e^x.

No, infinity can't be bigger than infinity. Different infinite numbers can increment in bigger steps than other infinite numbers though.

Can you name some real life use cases of infinity?
@siddude802118 күн бұрын
Yes, I've studdied complex analysis and analytic number theory for 5 years and in complex analysis you come across infinity quite alot. Well not in the same way shown in this video but rather singularities of a function. In fact if my momeory serves me right there is a theorem that states that every function can be expressed using its discontinuities but there is no neat formula for it. Also a conjecture I've been working on a proof for about 2 months now states that any analytic function f can be expressed as the sum of the singularities of the mellin transform of f times a first order root. Hence any analytic function f's mellin transform must have first order singularities so the first order singularities and first order roots terminates. I would also recommend watching some videos on the gödstein sequence where you use infinite ordinals to prove it always terminates

@@siddude8021 Right, but do you see infinity in real life? By that, I mean do you use infinity to explain or analyze real PHYSICAL things, not abstract concept?

@magnetospin well that's the thing, many of these theorems have real applications and although they might not be useful for the average Joe most of mathematics is not useful and made useful by engineers and physicists. Basically if maths is a language then understanding the language and its boundaries better helps us better understand how to apply this language to describe the world around us

@magnetospin I think a good example is the potential energy of a body within the gravitational force of another object. Then you imagine that you have 0 potential energy when you are at some point infinitely far away from the object. Basically F = G * m*M/r^2 then the potential energy = integral from inf to R of F dr = - G*M*m/r

The a-dimensionality of an infinitely small point on the numbers ruler is in contradiction with the modular a-dimensionality of a fractal. So, from a fractal point of view, the foundation of measurement is impossible.
@pentagon-math20 күн бұрын
That's something that's also amazed me. Startalk has an very insightful video that explains just this. What makes it even more exciting is that the fractal constructing any measured surface can be a decimal dimension!

nice! it can also be done by pattern recognisation. usually when we get a solution with an irrational denominator in the form a+b where either or both a and b are irrational, we are expected to rationalise it by multiplying by (a-b)/(a-b) which would hold true because it reduces to 1. so in a way this is a pattern I saw. the inside expression is in the form a+b where a and b are irrational. first I realised I cannot expand the logarithm into any form. So by my pattern recognisation, I thought of multiplying the inside by (a-b)/(a-b). And then I solved it. log((√13+√3)*(√13-√3)/(√13-√3)) = a log(((√13)²-(√3)²)/(√13-√3))=a log((13-3)/(√13-√3))=a log(10)-log(√13-√3)=a 1-log(√13-√3)=a log(√13-√3)= 1-a I am proud I have developed enough that I could do this in my head. you earned a new sub btw

lol if you try this on an actual Boolean computer it’s just like “if you say so” and pretends it’s false. Because meta data is a description and not a question. It just takes it as a fact and assigns it the value of false and moves on.
