My Identity As A Schoolmaster Has Been Exposed

Chapter 120 Five Kills!

“Moreover, what is wrong is what we have learned, Lin Mengjiao, tell him the idea of ​​the problem I just taught you.”

Lin Mengjiao looked at it indifferently, and smiled at the same time: “Hmm!”

He Junfei was dumbfounded and dumbfounded, but soon he returned to normal, and then he came to study hard.

Before giving him a topic, Lin Mengjiao persuaded: “Even I can see that you are eager for quick success! He Junfei, not everyone is Xu Cong!”

“The whole city, oh, or there is only one Xu Cong in the province, there can be no second one!”

Every word is like a depth bomb!

boom!

Boom! Boom!

Boom! Boom! Boom!

He Junfei lost all confidence in the explosion.

“Well, don’t be sad, just surpass yourself! I will talk to you about this question now.”

After a blow, Lin Mengjiao also began to explain the topic to He Junfei.

He Junfei listened carefully and found that he was indeed wrong, and the wrong was very outrageous. Finally, he understood thoroughly and thanked Lin Mengjiao, “I understand, thank you!”

“But Xu Cong, I still want to ask you the last question. I know that in your eyes, I am too eager for quick success!”

“I also admit that I want to be close to you too much! I want to reduce the gap between us!”

“But now, I know! Between you and me, I can’t compare with you in my life!”

At this time, Lin Mengjiao reminded him: “You can compare to other things without studying! For example, looks, hobbies, and so on!”

He Junfei almost spat out a mouthful of old blood. Are you serious about this?

“Compared with him? I’m not looking for death!”

“My hobby is only studying!”

Lin Mengjiao heard him say this, and said in embarrassment, “Uh… I’m sorry, I’m sorry.”

When Lin Mengjiao said this, He Junfei felt even worse, “After this time, I also know that people can’t eat fat in one bite. If you take a big step, you will suffer.”

“I have been thinking about this question for a long time, but I still don’t have a clue. I still hope you can help me!”

Xu Cong sighed and took the test paper, “Okay, look at the questions!”

topic:

The Chang’e-4 probe successfully achieved the first soft landing on the back of the moon in human history, another major achievement in my country’s aerospace industry. A key technical problem that needs to be solved to achieve soft landing on the back of the moon is the communication link between the ground and the probe.

To solve this problem, the Chang’e-4 relay star “Queqiao” was launched, which orbits around the L₂ point of the Earth-Moon Lagrange.

The L₂ point is the equilibrium point, located on the extension line of the earth-moon connection.

Suppose the mass of the earth is M₁, the mass of the moon is M₂, the distance between the earth and the moon is R, and the distance from the point L₂ to the moon is r. According to Newton’s law of motion and the law of universal gravitation, r satisfies the equation:

M₁(R+r) square + M₂r square = (R+r) M₁R cubic 750 squares, set a=rR, because the value of α is very small, so in the approximate calculation (3a cubic + 3a fourth power + 3a fifth Square) (1+a) square = 3a cubic, then what is the approximate value of r?

A. (M₂M₁ under the radical sign) RB.(M₂2M₁ under the radical sign) RC.(3M₂M₁ under the radical sign 3M₂M₁)RD.(M₂3M₁ under the radical sign 3M₁)R

Lin Mengjiao came over, she was dumbfounded, her head was about to explode, she said dullly, “What is this! It’s too scary!”

“Just looking at the options for this multiple-choice question, I’m scared to death! Damn! Under all kinds of root numbers!”

“Headache! Headache!”

Xu Cong ignored her, looked at He Junfei and asked, “Have you read the answer?”

He Junfei shook his head, indicating that he had never done it.

“I really want to learn how to answer this question! If it were you, what would you do?” He Junfei looked forward to Xu Cong.

He has no sense of temptation. He just wants to know what Xu Cong will do when he encounters this kind of problem.

Xu Cong, “There should be a lot of standard answers to this question. It’s scary. But if… give me the pen.”

“Set these M numbers to 1, and if you transform, the long formula above will be easy to solve!”

Xu Cong wrote lightly, and He Junfei didn’t dare to be careless and looked at it seriously.

“Convert the formula into this, knowing that R is 1, then alpha, that is, this α is R, and then this formula will be added to the formula of r.”

“Finally, it is 3r cube = 1, then what is r?”

He Junfei looked dumbfounded and said, “Yes, it’s three thirds under the root sign three times -!”

Xu Cong continued to analyze it for him: “Yes, if you put 1 in, you will find that only D option matches.”

He Junfei was stunned, and was immersed in thinking for a while. Lin Mengjiao looked at He Junfei who was stunned, and she murmured, “It turns out that no matter how powerful a schoolmaster is, there are times when he is confused!”

“He Junfei is not smarter than me!”

Xu Cong glanced at Lin Mengjiao, “Are there really people with insufficient IQ?”

Lin Mengjiao stuck out her tongue, “I don’t know if there is enough, but you are the only one who is far higher than ours, Xu Cong!”

The IQ of the average person is almost the same, but the difference in learning is too big!

Gradually, many parents will compare cleverness with stupidity. Over time, many people acquiesce to their own label. Before Xu Cong did not take the full score, would he be synonymous with “stupid”?

He Junfei came over in confusion for a while, looked at Xu Cong, and said gratefully: “Thank you! Thank you so much! Don’t bother!”

After He Junfei left, Xu Cong stretched. Lin Mengjiao took Xu Cong’s phone and played the game again. Suddenly she said to him, “You can play for me for a while, I’ll go to the bathroom.”

Xu Cong looked at the phone in his hand and shouted to her: “I haven’t played this game!”

“It’s okay, it’s said to be very similar to LOL, just play with you.”

In this way, Xu Cong began to manipulate the hero Lin Mengjiao played, whose name was Xuan Ce.

Xu Cong twisted his eyebrows, checked the hero’s skills, tried again after getting started, and checked some equipment.

“There are indeed some similarities with LOL.” After getting acquainted, Xu Cong tried to catch people and murmured, “What the hell is this hook?”

Xu Cong sat back in his study and turned on the computer, and checked Xuan Ce’s skills. After getting a general understanding, Xu Cong began to play.

He has hand speed!

He also has consciousness!

After all, he is a senior LOL player, the kind with a very high rank, Xu Cong has to do it.

“Uh! Didn’t this kill me?”

“Give me blood and ran away?”

The teammates also posted “666!, “Good job!”

Xu Cong looked a little speechless, “Uh…”

He found it very simple, and Xu Cong continued to master this hero.

“Just kill!”

one!

Two! Three!

After chasing the fourth one, Xu Cong felt that he could still kill! Finally, he crossed the tower and changed one.

Both the teammates and the enemy think that Xu Cong is the limit for one change! But–

Xu Cong changed his equipment in seconds, used the resurrection armor, and was resurrected!

Xu Cong, who left the tower, caught up with the opponent’s fifth hero, a mage with no ult, a full assassin, and a half-blooded opponent who had no ult.

The result can be imagined!

Kill!

Xu Cong Five Kills!
