Xueba God-level system

Wang Xiang looked at the countdown on the phone screen, and when there were only three seconds left, he smiled.After the resurrection with full blood this time, you can start killing, haha!

Finally, there was no countdown interface, and Wang Xiang began to launch an all-out attack. "Whoever dares to attack our crystals, I will let him go back and forth. One to kill one, two to kill one pair."

According to Wang Xiang's previous habits, he would never pay attention to the map on the top left of the phone.It's not because of anything else, it's just that I don't care to look at it at all.Wang Xiang does not have three eyes like Erlang Shen. One is used to look at the characters in the game, the other is used to control the buttons at the bottom right of the interface, and the third eye is used to look at the map.

But today, Wang Xiang subconsciously glanced in the direction of the map.It didn't matter at this point, it almost made Wang Xiang vomit blood.

The classmate was still staring at the question, silent.Looking at his demeanor, it seems that he will never give up when he is puzzled.But time is passing by every minute and second, but the situation of his writing has not appeared for a long time.

If it wasn't for Cheng Bite's good temper, he would probably have directly greeted him with "Wing Chun Boxing".

"Li Min, do you know it or not? It's almost time to go to class. You don't look tired, I look tired!" Cheng Yaotie couldn't stand it anymore. At this time, he had to say something. what.Otherwise, you may see that it is dark.

"What, what did you call me just now, Li Min? Stop teasing, I'm not Li Min." The classmate was stunned at the time. Does he look like he won the first prize in the competition?

"You're not Li Min, then why did you lie to me just now that you are, answer me quickly?" The veins on his forehead were exposed, and Cheng Bite was very angry.

That classmate just smiled slightly, but I had no way of knowing, and said, "Hey, Cheng Yaotie, can you be reasonable? I mean if I were Li Min, I didn't say I was Li Min. Min. What I said is just an assumption, assumption, do you understand? I just said, I want to become a person like Li Min, you can just be nice and sunny, and let me ask a question. If I If you refuse, you will look down on me. If I don't refuse, I can't do that question! After thinking about it, I think it would be better to do it, what if it does?"

Cheng Bitie's teeth were already gritted, and his face became much paler than before, "You, deceived my feelings. No matter who intercedes for you today, it is useless. You, eat I remember Wing Chun Shaolin Arhat."

"Stop." A crisp voice came from the door, but it sounded very familiar. "Cheng Bite, the person you're looking for is me, and I'm Li Min. What's troubling you, I'll take a look."

Looking at Li Hu who was not moving on the map, Wang Xiang was so angry that his whole body was itching. "Li Hu, you are standing in a military position. Why are you standing there without moving, the enemy has already attacked our crystal, and you should take action quickly."

"Wang Xiang, Brother Xiang, don't be angry, we have something to say, my phone is out of battery." Li Hu also mustered up his courage, and finally said these unspeakable words.

After listening to the words, Wang Xiang stopped talking.He passed out, and the phone fell to the ground with a "touch" along the arc of his arm, and the screen was instantly shattered.

You know, Wang Xiang spent a lot of money to buy the skin, ready to go to the silver rank.Unexpectedly, he and Bronze are so connected.

"Hey, Brother Xiang, wake up, don't scare me." Li Hu's tears rolled down his cheeks, but he seemed to be completely unaware, still shaking the unconscious King Xiang.

In less than 30 seconds, Li Min finished reading the topic.Get the paper and pen, I'm going to start showing off my skills.

As soon as they heard that Li Min was going to start calculating the problem, many girls in the class came over, and they also wanted to see how Xueba solved this problem.

Seeing that his roommate Zhao Liyang was also following other girls to join in the fun, Niu Zihao let out a deep "sigh", the first prize in the physics competition, is his charm so great?Forget it, I still go to my Gao Yaxuan to discuss the script of "Jing Ke's Assassination of the King of Qin" with her.

When Gao Yaxuan is not here, where will she go?Niu Zihao looked at the students around Li Min and shook his head.It's so crowded and crowded, that's all I can describe.

First, we need to perform a force analysis on point a. I won't write the word "solve", not because it is troublesome, but completely unnecessary. When you take the test, remember to write it.

As shown in the figure, it can be obtained from the meaning of the title:

f(oa)=g/cos∝, f(ab)=gta

∝, after writing these two formulas, Li Min specially emphasized it.This involves the knowledge of trigonometric functions in mathematics. What does it mean?It shows that mathematics and physics have a complementary relationship. If you don't even understand the basics of trigonometric functions, then even if you know how to formulate this question, it is useless.

Sine (si

), cosine (cos), tangent (ta

), these three concepts have already been learned when we were in junior high school, students who don’t know it, can go to the previous textbooks, there are detailed explanations in it, here, I just give a general introduction one time.

Let oa break first, then f(oa)=20√3n.Therefore, the oa cord can be pulled to an angle of 30 degrees from the vertical.

Many students don't understand, especially girls.

In order to make everyone understand, Li Min then drew a sketch.Those who don't understand will suddenly realize after reading the pictures drawn by Li Min.It turns out that this is the case, what kind of Olympiad problem is actually quite simple.

Li Min started the final summary work again. After the summary, this chapter is probably almost finished.

The general solution to this type of problem is: first assume that a rope breaks first, that is, it first reaches the maximum tensile force it can bear, and then judges whether the other rope has broken.If it is not broken, this value is the required value: if another rope is broken, that is, the force received at this time is greater than its maximum bearing force, then another rope needs to be selected as the research object and solved again.

After Li Min solved the problem, the whole class burst into thunderous applause.At the same time, Wang Xiang also woke up from the shadow of the failure of King Glory.

"Brother Xiang, you're finally awake!" Li Hu was crying beside him, and Wang Xiang was so frightened that he almost fainted again.
