The love of functions and derivatives

Probability has never been valued by students in previous years, and was even ridiculed by Lao Wang, a math teacher from a high school next door: "People who can't solve probability problems have poor reading comprehension skills, so they have to study Chinese hard!"

As a math teacher, Lao Wang was worried about his students' Chinese, especially when he saw that the student who was the first student in the class with a nearly perfect score in science and comprehensive examination had only two digits in Chinese, he felt distressed. My own baldness, grabbed a few hairs, and then tried to persuade me in the class: "You also need to work hard on Chinese. For a top student like you, whether you can be admitted to Tsinghua University or Peking University depends on Chinese. Look, If you pass one hundred and one in the Chinese test, it’s not too low, but if someone else takes one hundred and three, you will be dumped by twenty points..."

"Twenty points, where did you get it back? For a top student like you, the math, English, and science are all close to full marks, so you need to spend more time..."

The student who took the first place in the class defended himself in a low voice: "I only write Chinese every night when I come home from self-study, and I write until twelve o'clock..."

But the problem is that things like Chinese are metaphysics. Otherwise, how could he score more than 100 points to more than [-] points...

Lao Wang patted the shoulder of the student who took the first place in the class with a serious expression: "You haven't done enough work yet, keep working hard!"

What determines the status of each mathematical definition in the high school mathematics textbook world is the difficulty of the mathematics paper questions in the college entrance examination. The college entrance examination follows the principle of stability and change, and the status of each mathematical definition changes every other year.

Sometimes it changes less, and students scold the topic for being uninspired and undifferentiated, and sometimes it changes a lot, and students scold the questioner #$.*^!&#..$^&..%*$#.? %!But change and change, stability is the principle that must be followed, so trigonometric functions, solving triangles and sequences, the three brothers who share the same disease and pity each other, will always make soy sauce on No.17 question, and at most go to No.18 question to show their faces.

In previous years, the probability has stayed at the position of No.19 or No.20 in a tragic way.

And this year, the probability is finally proud—he has crossed the huge ladder from 21 questions to 21 questions.You know, Ellipse has been mixed in Question 21 for many years, and has never been to Question [-] once. He is considered to be the mathematical definition that is most likely to replace the derivative of Question [-]!Who would have expected that he would take this historic step first!

The first thing Probability plans to do after hearing the news is to hold a banquet and invite other mathematical definitions to participate.

Because he wants to take this opportunity to tell the world: My probability has finally become the No. 20 question in the national paper!
