Every time I see such a problem on the Internet, I get tangled up and complain for our students.

I think our students are miserable!

1, the basic theory of calculus was perfected hundreds of years ago, and we made no contribution;

Nowadays, there are many new theories, but none of them are established by us.

Perfect. On the contrary, I still don't want to make progress, and I'm still at the most basic level.

I'm just messing around after reading it. Open a calculus book written by 10,000 cats named Beast's Three Legs in Qian Qian,

There are many places where the concept is confusing and confusing. Up to now, there are still concepts of differentiability and derivability.

The world is a mess, and I have been pestering and beating for hundreds of years, making no progress.

Many screaming beasts fed by people's fat and people's cream are still misleading the poor children.

Calculus seems to have just been established, and it is being established, and students are asked to make some stupid questions.

What paper to write, completely teaching students as mentally retarded children. Shameless topic

Examples are as follows:

First, the application research of derivative;

B, the research status of determinant;

C, the research status of calculus;

D. new progress in the study of mean value theorem;

、、、、、、

What a pity! The landlord must have met a scum named beast.
