(Continuation from yesterday)

Recently, The discussion of "necessity of trigonometric function" works on the Internet.

A key figure says "I understand the necessity, of course, however, it is necessary for everyone isn't it? "

----

By the way , in my case, "if trigonometric function disappear, I will be killed outright next day"

To begin with, I cannot make any simulation program.

I have to give up analysing nearly all data.

If I don't use FFT(Fast Fourier Transformation), all hypothesis testing of mine will be aborted in my columns.

I will be hard pressed seriously.

However, I know that I am minority in the world.

I also can accept that the education about "trigonometric function" is despairingly boring and useless

I am irritated with the administrators who can have "trigonometric function" to be shamed.

Especially, the present math education process, like pushing students to rote exercise of formulas, should be destroyed at the bottom of my heart.

The essence of "trigonometric function" is not trivial thing.

-----

I am afraid that few people knows that the essence of "trigonometric function" is Buddhism. To be precise, it is not Buddhism but "Dharma teachings of Buddha" like "retributive justice" and "sense of mortality".

Believe or not, "Dharma teachings of Buddha" is equal to "trigonometric function".
