Rebirth 1977 Great Era

Chapter 484: Mathematics for liberal arts at the junior high school level, mathematics for science at the university level (Monthly ticket plus more)

After entering the examination room, the seats for today's examination were readjusted.

Candidates from arts and sciences sit together.

And everyone received a message.

This year's liberal arts mathematics test paper and science mathematics test paper are different.

The science students are surrounded by liberal arts students in front, behind, and around them, and the liberal arts students are surrounded by science students in front, behind, and around them.

In this way, even if you have good eyesight, you can't copy it if you want to.

Eliminate the possibility of cheating.

Then there were two new invigilators today, one holding the liberal arts test paper and the other holding the science test paper. After explaining the rules and precautions in the examination room, they began to distribute the test papers.

Even before today's test paper came out, I could clearly feel that the whole atmosphere was different from the first day.

If it was an appetizer yesterday, it’s like a meal today.

It is the final exam.

For those who do not take the additional English test tomorrow, you can be considered to have completed the college entrance examination by taking the test today.

I don’t know whether such a strict style was prepared in advance or because of something that happened yesterday.

After Fangyan received the test paper, before he even started to look at it, he heard the invigilator say:

"Candidates, please pay attention to your own test papers. Don't mistake arts papers for science papers. If you got the wrong paper, raise your hand and exchange it immediately."

Fangyan glanced at his test paper and saw that it said liberal arts.

There was no wrong test paper.

However, the difficulty of the questions above surprised him.

All of them are questions of junior high school difficulty.

Only the last question is a little difficult.

The topic is:
Given a quadratic function y=x- 6x+5.
(1) Find the vertex coordinates and symmetry axis equation of its graph;
(2) Draw its graph; the vertex and axis of symmetry formula of the quadratic function can be used to draw the graph of the function using the point tracing method.

(3) Find the coordinates of the intersection of its graph and the x-axis and y-axis respectively.

The test point is the graph of the quadratic function, which is a comprehensive graphing question.

When Fangyan saw this score-pulling question, the corresponding logic for solving it immediately came to his mind:

For the first question, you only need to solve the vertex coordinate formula and the symmetry axis formula of the quadratic function respectively.

For the second question, just draw the graph of the function according to the steps of listing, drawing points, and connecting lines.

The third question is to let X=0 to find the corresponding Y value, write down the intersection of the coordinates and the Y-axis of the function graph, let Y=0 to find the corresponding X value, write down the coordinates of the intersection of the function graph and the X-axis.

It can be seen from the title that the author of this question wants to test whether students can master the formula for the vertex and axis of symmetry of quadratic functions, can use the point tracing method to draw the graph of the function, and find the coordinates of the intersection of the function graph and the coordinate axis.

This point-pulling question was guessed by Fangyan and his friends last night.

But because they felt it was not too difficult, they did not pay too much attention to it.

At this time, Fangyan even felt that this was not a question that would help him get higher scores.

Then I looked over the previous questions again.

The result still found that this is the most difficult one.

No... Doesn't the math for liberal arts subjects now only test things at the junior high school level?
Aren’t liberal arts too boring?

Thinking of this, he wanted to take a look at the math problems of science students.

He had good eyesight and glanced at the math test paper of the science student next to him.

The content on the test paper made Fangyan stunned for a moment, it was actually college mathematics. The difficulty of the last few questions on the test paper seemed comparable to the score-pulling questions in the liberal arts.

Especially in the last question, it started to appear: using ε-δ language to describe the definition of the continuity of the function f(x) at the point x=x0.

Although it was not a problem for dialects, he could clearly feel the huge difference in difficulty between the two sets of test papers.

Compared to the simplicity of the liberal arts math paper, the difficulty of the science math paper is like hell mode.

At this time, Fangyan was already wondering whether the Chinese language test for liberal arts in the afternoon would also have this hell mode.

At this moment, Fangyan could clearly feel that the expressions of the science students around him were not very good.

I thought it would be difficult, but I didn't expect it to be this difficult.

At least there is a difference in style from yesterday's test paper.

There was only one score-pulling question in yesterday's test paper, but today's test paper gave them the feeling that the second half was filled with score-pulling questions.

At this moment, some people are already calculating how many points they will lose for the questions they cannot answer.

At this time, the invigilator handed out the test papers and said to everyone:

"Don't look around, keep an eye on your test paper, report any mistakes immediately so you can change them, and start answering when the bell rings."

Everyone fell silent and began to look at the questions on the test paper.

Fang Yan also withdrew his gaze and looked through all the questions on his test paper. At this moment, all the answers had already appeared in his mind, and there was no question that he didn't know how to answer.

As the doorbell outside rang, the invigilator announced that students could start answering questions.

In the simple math mode for liberal arts students, everyone did it very quickly.

However, many people were still stumped by the last question.

For the science students, doing the questions was like passing a level, and there were even more difficult levels waiting for them. Their expressions were solemn, which formed a huge contrast with the relaxed expressions of the liberal arts students.

Fangyan wrote quickly without any pause and wrote the answers one by one on the test paper.

Today's new invigilator also noticed him.

Seeing him write so smoothly without any pause, the invigilator was also a little surprised. Although the questions in the liberal arts are relatively simple, they are not so simple that he can write without any pause, right?

After walking around Fangyan and taking a look around, the invigilator discovered that all the answers had already been written on Fangyan's test paper.

The handwriting is neat without any corrections, the ideas for solving the problems are clear, and all the answers are completed in one go.

Even though the math test paper for liberal arts is relatively simple, the invigilator has never seen anyone who can do it as well as he did.

The two invigilators took turns looking at Fangyan's test paper behind his back, then silently exchanged glances, and saw praise in each other's eyes. This clear and quick way of solving the problem alone is not something that ordinary people can have.

It’s just a pity that he didn’t get the more difficult science and math test paper, otherwise it would have been possible to see whether he can achieve his current level.

Fangyan had just finished his own test paper and was also observing others.

Here, when it comes to math, if you know it, you know it, and if you don’t know it, you don’t know it. Some people’s faces turned red and their scalp got dandruff from scratching, but they still couldn’t figure it out.

Of course, there are also some people who suddenly figured it out, and started writing quickly with excitement on their faces. This is like someone who suddenly got it in the exam room, and performed exceptionally well in the exam, which is a rare state.

However, Fangyan was somewhat fortunate that his younger brother and older sister both applied for liberal arts.

In this way, these questions will not be difficult for them at all.

Especially since my little brother is weak in mathematics, considering the difficulty, it is not a problem for him at all.

As long as there are no problems with the Chinese language test this afternoon, they will have a sure chance of getting into Peking University.

PS: I got another hundred monthly tickets, so after finishing this chapter, I still owe you 20000 words.

Just got home, there's another chapter later.
