Zhou Tai saw Yan Feng's reaction, but pointed to the black face on the podium, but Zhan Fei thought that the black face asked him to answer the question, so he rubbed his eyes, looked at the things written on the black side on the blackboard, and then said directly: "According to the vector projective theorem, its projection is equal to the modulo multiplied by the vector..."

And when Zhan Fei started to speak, Heimian was stunned, because this topic was written down by him and prepared to be talked about in the next class, and half of what was used in it was the vector projective concentration that he talked about in the previous half an hour, and it also involved the problem of the mixed product of three vectors, which he hadn't talked about at all.

This little guy who has been sleeping in his own class has no difficulty in explaining this question?

College mathematics, just to cope with the exam, in fact, is not difficult, and the difficult place, is to really grasp the knowledge, understand the concept, if you can't understand, then rote memorization to pass the exam and cheating to pass the exam, the difference is not big, but the former is to cheat a small note to the brain, and then is written on the note, and how to understand it?

Flexible application, combining several concepts together, being able to analyze and solve them clearly, is flexible application, and as far as Black Face knows, almost no one in the class can do this, they know that one plus one equals two, and they also know that two plus one equals three, but if the three add up, they won't count.

Therefore, Hei Mian deliberately came up with such a problem, combining the two knowledge points together, training the minds of these students, and preparing for several of them to participate in the mathematics competition, but before he could speak, Zhanfei had already solved this comprehensive question without the slightest problem.

And through Zhanfei's words, Hei Mian can also feel that Zhanfei's thinking span is very large, even larger than the span of his analytical geometry teacher for many years, he has to turn his head to know the intention of Zhanfei to say a certain sentence, as for the students below, they can hear it completely in the clouds.

And two minutes later, Zhan Fei finally finished speaking, and the black face said that he bowed slightly, and then said: "Sit down, Zhan Fei let me see what it means to be a genius, people slept in a class, and still easily answered this comprehensive question."

And the span of thinking is so large, the methods used are ingenious, even I, the teacher, are ashamed of myself, our department is really a hidden dragon and a crouching tiger, there is a math competition next month, the original third candidate has not been determined, Zhanfei classmate, it's you! ”

Hearing the words of the black face, everyone looked at Zhanfei in surprise, although Zhanfei performed well last time, it was only good, but this time, it was completely different, even the black face called Zhanfei a genius.

Who is Blackface? The vice president of the Bozhou Institute of Technology, he himself is a doctor of the Department of Mathematics of Tsinghua University, he has taught in Bozhou Institute of Technology for many years, and there are seven or eight departments of mathematics majors in the whole college, all of which he is responsible for teaching.

And in Han Ling's mind, Zhanfei's reading like a book flipped, could it be that this guy is really a genius as Hei Mian said? And at that terrifying speed, if you turn the book through it, you can fully understand what is inside? That's too wicked, isn't it?

And Zhanfei was also stunned for a moment, and then sat down, the title of genius, he used to have it before, but it was when he was in elementary school, junior high school or high school, when he went to college, he was out of sight, I didn't expect that after so long, I heard this title again, and I felt that it was really good.

The math competition, it sounds quite interesting, there is still a short period of time before the exam, and I have to wait for a while if I want to get a high score to show my mother, but today is the 25th, and it is not long before the math competition, and when the time comes to get a medal back, my mother will be very happy, right?

However, with my current knowledge, if I want to win the ranking of the provincial mathematics competition, there may be some shortcomings, right? Well, in a moment, go to the library to recharge!

After taking the black-faced class, Zhanfei left the classroom, and then went straight to the library, there are a lot of books on mathematics in the library, among which Zhanfei and their textbooks are only more than 30 books in four years of college, and there are a large number of books, many of which are translated from the works of some foreign mathematicians.

These books are very beneficial to Zhanfei to expand his knowledge, he stayed in the library for two hours, and it was not until more than one o'clock that Zhanfei went to eat, and then went to the library again, and Zhanfei also lived a hard study life similar to Liu Yuan.

Of course, Zhanfei's efficiency is much more terrifying than Liu Yuan's, and it is also much faster than his own, because after this upgrade, his intelligence value is already as high as twenty points.

The next morning, the sun was shining, and Bozhou Institute of Technology also ushered in the annual summer sports meeting of the whole school, and each class, according to the original plan, sat down around the playground, and showed the position of their class, which happened to be not far from the rostrum, and more than 20 people in the class sat in a small phalanx.

No one was absent this time, after all, it was an annual sports meeting, and the school was relatively strict, and the class leader needed to count the number of people, so those who usually stayed in the dormitory also came out to see the sun.

After everyone sat under the sun for about ten minutes, it was finally half past eight, and on the rostrum, a group of teachers and hosts also walked up, and then, the host said: "The wind is beautiful, the sun is shining, our Bozhou University of Technology ushered in the 2014 Summer Games..."

Then came the long nonsense, and after four or five minutes, I finally got to the point: "First of all, the men's 100-meter preliminary race, okay, next, please come on!" "The school sports meeting, naturally, there are not too many rules, can be completed in one race, there will definitely be no preliminary finals, but sprinting is no way, because sprinting is not like long-distance running, dozens of competitors can run together, sprinting because of the distance, everyone must occupy at least one track.

The school playground has only eight tracks, so it needs to be carried out in separate batches, the 100m, 200m and 400m plus the preliminary race of the 4x100 relay will be the main events this morning, and each event will be men's and women's first, and after the completion of these events, the men's and women's long-distance runs will be carried out directly.

In the case of long-distance running, the finals are held directly, with dozens of competitors running together, and after the completion of the men's and women's long-distance running events, the finals of each sprint event will be held, and those sprinters will also have a break, and as for the shot put, other competitions will also be held at the same time.

Because there is no hard time requirement for these events, if there is a conflict with the track race, it is okay to go later, and then, the boys in the class who participated in the sprint also played, and it can be seen from their expressions that they do not attach much importance to this race, but only participate.

In fact, most of the class players have this attitude, because Bozhou University of Technology, there are sports students, and every year, in the sports meeting, all the awards are basically won by those sports students, and the other class players, even if some are talented, are difficult to compare with those professional players, so everyone is just joining in the fun.
