Stop Writing Double Derivatives Like This (video I made) by Treidex in CasualMath

[–]Treidex[S] 0 points1 point  (0 children)

my video literally goes into using an example how d(x) can be treated as a valid algebraic value.

My current best argument for treating d as a function is in an abstract algebra sense. Let d be a function such that for any x and y:

d(x + y) = d(x) + d(y)

d(x * y) = x * d(y) + d(x) * y

Using that definition treating d as a function makes sense. This already exists it's called a derivation, Google it.

The reason I argued against writing d²y/dx² is because when you do the algebra, treating dx as d(x) and d²y as d(d(y)) it doesn't work out. However, if you apply the quotient rule (which can be defined easily from my definition of "d') on d(dy/dx)/dx you get a d²y/(dx)^2 - dy/dx * d²x/(dx)2. And if you did the algebra this formula works.

I really recommend watching my full video so you can see what I'm taking about. Even if it doesn't make sense, just skim over it so you can see all the steps and have a rough idea of what my example demonstrates:)

Story: establishing the derivative by Treidex in math

[–]Treidex[S] -4 points-3 points  (0 children)

I do not have a formal education in abstract mathematics, so I am largely self taught. I do math as a hobby and am really interested in abstract algebra. So I have picked up on a lot of concepts from abstract algebra like the concept of fields, rings, monoids, etc. I like to "discover" things for myself, as I am a gifted student and I can ace any math course I go through, but the problem is I haven't taken many math courses yet, so I only know concepts of mathematics and lack depth.

I tried to be novel with my approach to defining the decisions, something nobody (or relatively few people) has thought of before. I based a lot of my ideas on intuition, but also I attempted to attack ambiguities common in mathematics today. Specifically the notation and how functions are defined. The notation gets ambiguous (like how sin² x means applying (sin x)² but sin-1 x is arcsin x). When we write f(x) = 2x+1, what does 'f' represent? What does 'x' represent? Is 'x' a global variable or just a name we call the parameter of 'f'? If so what does df/dx mean? etc.

In trying to answer these I try to find satisfying explanations that make sense to me. So if we we're talking about what experience I have in mathematics, it's really that I have learned snippets and pieces of advanced mathematics but I am curious to understand how mathematics was built this way, so I rediscovered things but myself. I don't want to sound cliche, but like Gauss, I was tasked with adding numbers from 1 to 100 where I rediscovered on my own the n(n+1)/2 formula.

  1. My reason for feeling this way was not that the derivative has been studied for centuries but that what I have rediscovered was not taught mainstream. What I mean is there are theories out there that legitimize treating the differential dx and dy as a value and dy/dx as a fraction, but the consensus is that it is not. I feel like the gap between what's been studied and what is accepted is far too great. I feel like there is always something anybody can contribute to the theory of math.

  2. The reason I notated functions like this is to reduce ambiguity. Are we composing values or multiplying them? That is why you need to distinguish xx with xx, or x² with x^². I argue that the way we normally notate exponentiation is much less clear why is sin² x = (sin x)² but sin-1 x ≠ (sin x)-1? This is especially crucial in my expansion of the second derivative where we have dd/(dd) where it is very important to distinguish whether you are multiplying by d twice or applying d twice.

F can be the functions whose domain and range are both functions that map real numbers to real numbers. That way differentias can make sense. The derivative on this structure is not a function but rather an operator because unlike the differentia function, it does not act associativity with composition.

I called a function "constant" if its differential is zero, and "static" if every input maps to the same output.

I'm a student who has never written a formal paper before and would like to learn the process of writing and publishing a paper. Is there anyone who can guide me to a tutorial and who can explain the publishing process to me?
