(Continuation from yesterday)

Trigonometric functions have two properties.

The first one is "tool" called "ruler".

This is what the current high school mathematics is aiming for, however, most students are unable to find their significance.

Trigonometric functions are not mere rulers, but it is a useful tool, for example, this function give us three unknown information from only one piece of information, like Detective Conan is also a pale blue.

It is something like a "motorized chain saw" for "sawtooth", and "electronic rice cooker" for "kamado".

The second is "tool" called "decomposition".

This is the method I quantitatively measure "wave" I talked about yesterday, in the current higher mathematics, it is a tool that does not appear at all.

That is what Fourier's theorem (argued by Jean Baptiste Joseph Fourier, Baron de) is found, can be expressed as a series of trigonometric functions.

I could use this Fourier transformation to set up the hypothesis of the phenomenon that "we can not continue a diet for two consecutive months or more".

The tool called "Fourier transform" succeeded in showing "teachings of Buddha" logically, mathematically, quantitatively, after the time of 2000.

By the way the story will change,

It seems now that my friends and I have predicted quite accurately that "China (the continent) will become an economic superpower of the present world" at the stage of 1994 .

We have conducted various thinking experiments on "disturbing work" to make this Chinese economic powerpower - in the car.

In our conclusion, we reach to the agreement in opinion that "interference with mathematical education" - "trigonometric function is not to say, we have not to let the people take over the concept of differential integration absolutely" .

Because,

(1) The government that acquired this concept, will be able to accurately analyze and predict internal affairs, diplomacy, and especially military (including weapons development)

and,

(2) The public will be able to verify the policy of the government and will be able to trust the government

In that country, the former national leader had shut down the economic powerhouse itself by "selfish policy" that "tools of mathematics should not be handed over to the hands of the people".

For our country who was proud of Asia's leader (in peaceful sense), the "politicians policy" on this continent was truly appreciated.

Not only in the continent but in the imperialist era, "politicians' policy against the strong colonies was truly important. Especially, regarding "mathematics education" of the strong colonies, it had to be sealed within the range of "four arithmetic operations" absolutely.

Also, in modern times, it is like a piece of cake, such as knowledge of mathematics and cyber attacks on nations with low understanding.

A nation that does not understand the dependence of mathematics in cyber security is decided to be lost, not logical but sensually.

As for this, I think that it is easy to understand simply by receiving a shameful defeat in the decryption game in WW2 against war against Germany and Japan.
