I thin that someone do or say something about "trigonometric function".

Two years ago, my released column,

"Recurrent Education [the former half]: The trigonometric function unnecessary theory and the Destruction of Individuality"

is now ranked in, so I was surprised.

Probability, this argument of "The trigonometric function unnecessary theory" will often be happened in the future.

However, rather than the above column, in the latter half,

"Recurrent education should be a "guidebook" for survival in the age of career abandonment".

I have argued hard opinions of mine like following,

"You say a lot of things, but the bottom line is that you guys just hate trigonometric functions: ..!"
