(Continuation from yesterday)

To understand "trigonometric functions" is to understand "wave" in the end.

And the world is "overlapping" of "countless waves".

"Wave" is a phenomenon that fluctuates with constant amplitude and period.

Everything from politics, economics, diplomacy, education, to our body and mental health, physical condition are all "waves".

One of the concrete things that appears as an overlap of this "wave" is "luck / bad luck" that we call.

-----

Looking at this from "Buddha's teaching".

- "Beyond heartlessness" means that each "wave" will constantly fluctuate. It is sin (t) when t is seen as a time parameter.

- "Various lawlessness" means that all waves (living things, inanimate objects, natural phenomena) are affected by mutual waves. This is the same as Σsin (t_n + α_n).

- "Nirvana Lonely Peace" means that if the world knows that the world consists of movement of waves, life can be lived in a vaccine.

- "All things are causes of sufferings"is a summary of the three above.

"Everything can be divided into three types of "easy","pain","normal". When "easy" also breaks, and becomes "pain". And "normal" is all impermanent and it can not escape the change of life. Therefore, there is nothing that is not "pain"."

In other words, it means "It can not be helped even if we are scared."

-----

It is equally difficult to keep feeling "unhappy" as it is difficult for us to keep feeling "happiness".

If you feel that "unhappiness" is going on, you need to increase the width (amplitude) of the waves or raise the bottom (intercept)

The teaching of Buddha is "teaching" which explains the above very logically.

In the beginning, Buddha's teachings will not include any transcendent (God).

-----

(1) This world is made up of "waves" generated by multiple events

(2) If you can see the essence of those "waves", you can live relatively easily

Buddha said, "Do not depend on God" "If you understand the wave (= trigonometric function) of this world, you can become happy."

-----

If you understand Buddha's teaching "The world is an overlap of waves", Every time you feel sick, you do not need to purchase and read a book called "books when falling down" or "teaching wise men" at convenience stores.

Buddha's teachings say that (1) the world is basically uncontrolled, but (2) it basically repeats, so (3) the depressed mood always returns to its original (unless it is a psychogenic disease).

-----

However, Buddha told us that "This world is understandable by "overlap of waves" but he did not tell us how to quantitatively measure and measure of "wave".

Although the basic concept of trigonometric functions existed during the Buddha era, we had to wait for about 2000 years to be found a new measurement of frequency conversion as a function of time.
