Some people on the forum told me that solutions to this problem cannot exist, since the square and round ones do not appear to each other (as I understood it), but after experimenting a little with plotting on WolframAlpha, I decided that this is a fundamentally wrong approach. As it turned out, the whole thing is just in "quantum entanglement." But first things first.
How to model entanglement? We have direct and inverse trigonometric functions, there is a variable x-photon and several trivial operations. The first thing that comes to mind (at least to me) is to look at the graphs of the functions ArcSin [Cos [x]] and ArcCos [Sin [x]]:
The given graphs already remind us very much of the āquadratic cosineā we need, but something is missing, it turns out that there is not enough āentanglementā, what we did is in fact the first level entanglement, but this is not enough, you need these two functions build, coming to the confusion of the second level. After several experiments with the available trivial operations, I stopped at the division and this is what happened (Fig. 4):
')
It was here that I realized that I was not lost in the entanglement of the x-photon and everything just clears up.
It would seem that half the problem is solved and it remains stupid to copy the solution into two formulas of the form:
But I wanted to present everything with one formula and the search continued ...
Therefore it was necessary to analyze the graph presented in Fig.4. What is remarkable about it?
First, half the square is present, but you need to get rid of these ascending lines. How to achieve this? Only āannihilationā, that is, self-destruction of opposites. And it is here that we will need a module so that we have smooth, ascending and descending symmetrical lines. Therefore, I considered the following schedule:
It would seem that a small difference is a module, but a big difference - now we have symmetric (relative to the origin) ascending and descending lines, which are sufficiently āfoldedā and they will turn into a square ... But you donāt need to add them;
Q.E.D.
This feature
y=ArcSin[Cos[x]]/ArcCos[Abs[Sin[x]]]
I called the ā
white function ā because it is as perfect and harmonious as the white color.
The white function is a complex function model of a quantum-entangled pair of argument x with itself.
The white function also defines a whole class of like trigonometric functions of the form
y=ArcSin[f1[x]]/ArcCos[Abs[f2[x]]]
for example, this view can also include the function
y=ArcSin[1/Tan[x]]/ArcCos[Abs[Tan[x]]]
etc.
