I may be a pseudo-scholar

Chapter 100

Those who have taken the test know that many concepts are somewhat vague. If there is a method of elimination, choose the best method, and you can pick out the most perfect and reasonable option. However, if you are asked to choose the right one of these concepts A few words, those vague concepts will make you very entangled.

Choose or not choose?
Bai Xue was also tangled up.

To be honest, Bai Xue has a fairly deep understanding of the concepts of parallel and vertical, but one of the plane segments is vertical, and because he hasn't done it for a long time, he can't be [-]% sure of his choice.

"Forget it, let's continue to do it first." After Bai Xue wrote down the answer he thought, he continued to look down.

"I thought it was quite simple, but now it seems that this year's paper is much more difficult than last year." When Bai Xue chose the seventh question, he once again felt the deep malice from mathematics.

This math problem is even more awesome.He described the Yang-Hui triangle for you in the form of classical Chinese.

After all, Bai Xue was at the LV5 level of Linguistics. This bit of classical Chinese, Bai Xue was not in vain. Soon, he chose the correct answer.

However, many scumbags in Chinese or classical Chinese are not so lucky.

They looked at the seventh multiple-choice question eagerly, and fell into deep thought again.

Four and ten minutes have passed since the exam, but many people haven't even finished writing the multiple-choice questions yet.

There are twelve multiple-choice questions, one of which is worth five points. Under normal circumstances, it takes about half an hour to answer them all. Otherwise, there will be no time to do the big questions later, but the difficulty of this year's college entrance examination has made these candidates feel anxious. , with a layer of frost.

At this time, Bai Xue was working on a big problem.He also felt the pressure of this year's college entrance examination.After all, according to his usual strength, Bai Xue had already finished the math paper in four or ten minutes.

"This final derivative question actually has transcendental inequality and L'Hopital's law?" Bai Xue frowned, and the pen in his hand did not drop for a long time.

The final question in mathematics every year is derivatives.This is a powerful problem that can make teachers despair, make students want to jump off the building, and make parents sigh helplessly.Usually, less than a hundred candidates in the province can completely answer this question, and the average score of this question in the province is no more than two points at most.

Twelve points for the big question, no more than two points, this is the scary part of the finale question!
Bai Xue is now stuck on (2) of this question, which is the last question.He has an idea for solving this question, and he knows what to do. He has even searched for the answer and knows it clearly, but he doesn't know how to write it down.

Yes, as a big guy who has studied advanced mathematics, he did not solve this problem by using the common method of separating constants and replacing elements in high school. Instead, he directly used L'Hopital's rule and Taylor series in advanced mathematics to convert This question is instantly killed.

But there is a problem.

These awesome things that Bai Xue uses are not allowed to be used in the college entrance examination!
Super-class formula, no points for the college entrance examination!

However, Bai Xue really didn't think about how to use the knowledge he learned in high school to solve this problem.

This question is a question about the parameter range of the constant establishment problem, even in mathematics competitions, there are often such questions.The general method of such a problem is to find the derivative, separate the parameters, and then solve it with advanced mathematical knowledge.
