NPC Nine-Tailed Fox

Chapter 170 Show IQ Face Slap "Contest"

The Vornos' theorem was displayed on the projection screen, while in front of the blackboard, Ji Xi and Yu Wei were standing at opposite ends, each holding a piece of chalk in their hands.

"Let's get started," said the calculus teacher.

Yu Wei got into the mood in an instant, and started writing quickly with chalk and mental calculations. He glanced out of the corner of his eye and found that the teaching assistant just stood in front of the blackboard and didn't start writing. It seemed... that he couldn't write?

He couldn't help but sneered in his heart, just like that, still trying to show off?His head was run over by a truck just now, and now he regrets it so much that he can't wait to find a crack in the ground.Hehe, I don't care how much I weigh.Later, the teaching assistant who only has a good face, just wait to be slapped in the face severely by him.

After Yu Wei glanced at Ji Xi contemptuously, he withdrew his scrutiny and continued to work out his own problems.

After writing a lot, Yu Wei almost reached the bottom of the blackboard when Ji Xi started to write, but he did not rush.

When the final conclusion came out and the full stop was drawn, Yu Wei stopped holding the chalk and said loudly, "I'm done."

At the same time, Ji Xi on the other side of the blackboard also stopped writing.

The students in the classroom, the calculus professor, and the bosses behind were all watching the two calculations on the blackboard.

At this time, the blackboard was clearly divided, one side was densely packed, almost like a pile of termites, and the other side was empty with a few lines, like a few white sesame seeds sprinkled.

After Yu Wei announced that he had finished the calculation, he looked to the other side of the blackboard with a sullen expression.

He wanted to see that the teaching assistant had really calculated the result, but when he looked, he found that it said: "From the above, it is impossible to prove Vornos' theorem with the calculus knowledge learned in this course. "

"Hmph, if you say it can't be established, then it can't be established? You are talking nonsense with your eyes open. Haven't I already written the method?" Yu Wei opened his eyes wide.

"I wrote it wrong at the beginning of the second line." Ji Xi's voice drifted over coolly.

Yu Wei opened his eyes wide and wanted to refute, but then he heard the teaching assistant in front of him continue to say:
"The equal sign is wrongly connected between unequal functions. This is the first; because there are many variables involved, the derivative and partial derivative of the implicit function are confused in the middle. This is the second."

Yu Wei's eyes looked at what he wrote on the blackboard, but Ji Xi's words still did not stop in his ears.

"Although the calculus for finding the limit by sub-item of the law is correct, the decimal point is marked with a wrong digit in the result."

Yu Wei's face gradually darkened as he saw that his rather proud calculation was so criticized.

Unfortunately, he didn't know that the heaviest blow had yet to come.

Ji Xi's voice was very cold, and he said in a deep voice, "But these are just minor problems. The point is, your thinking about solving the problem was wrong from the beginning."

"Impossible!" Yu Wei was still dissatisfied, "What you just picked out is just a small flaw, as long as you solve these, you can get the answer!"

He took the chalk and continued to recalculate on the blank space of the blackboard, but as he was writing, he realized that he really had made too many mistakes just now. The more details he picked, the more mistakes he made. Once corrected, he can calculate in front The road completely changed direction.Not only has the direction changed, but it has become increasingly difficult to walk.Just like what used to be a smooth and broad road, it is now a rugged path. It is still unknown where the path leads and whether there is a road ahead.

He counted and counted, his heart became more and more uncertain, and he suddenly felt that his thinking might be really wrong.

Ji Xi's words continued: "Derivation of continuous partial derivatives..."

"Enough!" Yu Wei interrupted him, biting his lower lip, his eyes were red.

He was still counting, but unfortunately, in the end, the small path led to the cliff, and there was no way to go.

The conclusion is that it is impossible to prove Vornos' theorem with the calculus knowledge I have learned so far.

Yu Wei froze in front of the blackboard.

Ji Xi said: "This problem cannot be solved with the calculus learned so far, but it is feasible by combining the solution geometry and line algebra. Do I need to tell you?"

Hearing this, Yu Wei was instantly humiliated, his eyes widened, and he said out of his throat, "No need!"

"Say it, tell it, we want to know!" A girl shouted from below.

Ji Xi glanced down, and found that among the crowd, Lin Xiaolin didn't care if he knew it or not.And she also yawned, her eyelids drooping, like a sleepy kitten, wanting to go back to sleep in its soft nest.

The calculus teacher also said: "Since some students want to know, then..."

"Since he said he doesn't need it, forget it." Ji Xi said coldly, and then said, "Mr. Wang, isn't it time for class to end, and it's time to end get out of class."

The calculus teacher was taken aback when he heard this, and looked at his watch, only to realize that the end of get out of class time had really passed, about 15 minutes had passed.

He said: "I'm sorry, students, I accidentally procrastinated. Let's end the class now. But before the end of the class, let's give our teaching assistant... er, and Yu Wei. Applause, thank them Ah, what a fantastic problem-solving contest for us!"

As soon as the words fell, the students in the classroom, including the few big men behind, clapped their hands vigorously. Of course, only they knew who their applause was dedicated to.

In just a few short lines, he demonstrated concisely, directly and rigorously that "using the calculus knowledge they have learned so far is not enough to solve this Vornos' law".It can be said that it was a powerful slap to Yu Wei who was always looking for a sense of presence.

Who else could this applause be for, besides this handsome and abstinent teaching assistant with a high IQ?

Lin Xiaolin also clapped her hands hard, her eyes lit up instantly, but the reason is because get out of class is finally over!
When everyone was clapping, the calculus teacher looked proud, as if the person who had just appeared was not the new teaching assistant in front of him, but himself.

He looked at Ji Xi and said, "What you just said can be solved by using the calculus knowledge you have learned so far combined with analytic geometry and linear algebra... that, can you tell me."

Ji Xi nodded: "I'll send the calculation process to your mailbox when I go back."

So the calculus teacher smiled contentedly, and felt that he was out of class, and then put on a sophisticated look, as if he also knew the calculation method, but he just wanted to follow Ji Xi. Just discuss and learn from each other.

At this point, a farce can be regarded as over.

get out of class is over and everyone has dispersed.

Lin Xiaolin unplugged the fully charged mobile phone from the power bank, quickly packed her schoolbag, and walked out of the classroom with everyone.

While walking, she turned on the phone, and just plugged in the earphones to listen to music, when suddenly, someone in front blocked her way.

Lin Xiaolin looked up and saw that it was Yu Wei.
