Third-order solution of Baidu cloud in classical Chinese
1. Get the electronic version of classical Chinese to read the third order. I am too hesitant to make up for it, but please ask again: Do you want to do it? Dan, please ask Qin Wuyang to move forward! Jing Ke angrily rebuked his wife and said, Today, those who oppose it stand up! It's too late to take the dagger to test now. Those left behind by Qiang Qin's servants will entertain our guests. Please resign and decide! So Mrs. Fife and the guests who knew about it were all dressed in white and sent to Yishui. Grandfather stepped onto Gao Jianli's Jing Ke Song Road, and all the singers wept bitterly. Before the song, it said: the wind is rustling, the water is cooled, and the brave are revived! After generous feather, people are crowned in Jing Ke, and the car is finally done. Since Qin held a thousand dollars, Meng Jiajia, the favorite minister of Qin, first said to Qin: I'm really afraid that Wang Wei dared to dispatch troops and refused to pay tribute to the county minister, guarding the ancestral temple of the first king, fearing that Chen Jin dared to cut down the fan, offering a letter of worship to Yan Dukang and sending it to the court. So he heard Wang Wei's order, and Wen Xi dressed himself in royal clothes, and invited nine guests to see Yan. An envoy took photos and sent them. The poor dagger surprised the king of Qin when he saw that he was holding a dagger in his left hand and a dagger in his right hand. I'm afraid I'll draw my sword in a hurry and put it in my room. Jing Ke drove Zhu away, and the ministers were stunned and at a loss. Qin's attendants hold rulers; All the Langzhibing were summoned by Chen Dianfei's imperial edict, so Jing Ke rushed after the Qin king's pawn, and his hand * * * fought for the doctor Xia, and his medicine bag Qin pawn, anxious to know the left and right, said: Wang negative sword! Wang negative sword! Then he hit Jing Ke and broke his left leg. Jing Ke led him to lift the dagger, lift the pillar of the king of Qin, lift the pillar of the king of Qin, and then hit the pillar of the king of Qin, playing eight pieces of self-knowledge leaning against the column and laughing at the basket. He said: "If you want to rob, you must make too many appointments, and you must behead King Jing Ke for a long time." 5438+0. Add the same meaning to the sentence () A.① Suspicion of repentance is a re-invitation; The minister's special desire for food is a step of self-improvement; B.① Qin Wuyang entered the mountain with a picture frame; (2) the axe smashed into the forest; C.① Qin's left hand holds a dagger in his right hand; 2 force my heart; D.1 self-knowledge, leaning against the bar and laughing; 2. Fold dead wood; 12. See the wrong item of Jing Ke's image evaluation in Two Bs. After careful consideration, bribing Meng Jia with a large sum of money plays an important role in deceiving the king of Qin to successfully implement the assassination plan. Chen Shaohua calm down, let Qin Wuyang, Qin's fear look aroused Qin Junchen's suspicion. Fortunately, Jing Ke tactfully resolved D.' s loyalty and sincerity, and Jing Ke hoped to capture the king of Qin alive and seek Qin Yan's long-term reward, Dan Tai 13. Jing Ke chased the king of Qin, Qin, and all his ministers were surprised and lost their intention. (4) Reference answer: 10. C (tolerance and forgiveness) 1 1. B(B All prepositions are consistent; A 1 conjunction in 2 adverbs only C 1 preposition uses 2 prepositions to modify the translation and D 1 conjunction list. 12.a (Jing Ke did not yield to power) 13. (1) (omitted) (implementation of anger angle) (2) Jing Ke holds a picture with Tu Tu to show all the daggers (implementation meeting) (3) Jing Ke chased the king of Qin and the king of Qin to run around the pillar, not surprisingly, suddenly he didn't want to go home at all (implementation of footwork). You can say goodbye to the teacher now. With a dagger, Qin's death is hard to predict. I want to wait for my friend to say goodbye now, because it's too late. All the guests were dressed in white clothes and white hats to bid farewell to Yishui. Gao Jianli is creating Jing Ke's music and making sad sounds. Everyone is in tears. Jing Ke sang before he went: The wind is rustling, the brave are cold, the relapse is fierce, and the generosity is full of eyes. The hat is off. Jingke's car has never given a generous gift. Meng Jia Meng Jia, Minister of Qin, said in advance: The prince of Yan is really not afraid of the king of Qi. You dare to send troops against the king. You are willing to take the whole people as the king. Like Qin county, you can pay tribute to Qin and ask for a temple. You're not afraid to make a statement. Now I'm going to cut off Fan's head and present the picture of the satrap of Yan State with a swallow in a box. The court will send some cautious people to tell the king to listen to you. You tell the king to listen to you. I'm not happy to put on a royal dress and set up a ceremony for nine guests. Xianyang Palace received Yan's envoy. Jing Ke is holding a box with Van Yuqi. Qin Wuyang was afraid of changing his face. His ministers were surprised that Jing Ke left with a smile. Before Qin apologized, he said, I didn't see anything in the far north. I hope the king can forgive me a little, so that I can complete my mission in front of the king. Qin Jing Coe said: As Tu Tu, all the daggers are exposed. Jing Ke seized Qin sleeve with his left hand, and stabbed Qin with his right hand without a dagger. Qin stood up and broke his sleeve. The sword is too tight to carry the scabbard. Jing Ke chased Qin and ran around the pillar. The princes were not surprised. Things suddenly don't want home. They are all rude. According to the Qin law, the palace served the princes and brought some weapons. Armed guards didn't make the temple in an emergency, so they asked Jing Ke, the bodyguard, to go after the Qin family. There's nothing to pay Jing Ke. He only used his hands to fight with Jing Ke, a Qin doctor, and threw his medicine bag at the king of Qin in Jing Ke. He ran around the post in panic and was at a loss. All the officials reminded him that Wang Kuaijian had his back to Wang Kuaijian and his back to the king of Qin, drew his sword and stabbed Jing Ke, cut off Jing Ke's left leg, and Jing Ke was disabled. He raised his dagger and threw it at the king of Qin. He missed the pillar, cut down Jing Ke in Jing Ke, and was wounded with eight swords.

2. What is a third-order determinant? First, calculate the third-order determinant with an example. A, B, C, D, E, F, G, H and I are all numbers. Calculate A*E*I, B*F*G, C*D*H by diagonal, and then sum AEI+BFG+CDH by diagonal. Sum the values of CEG+DBI+AHF determinant into (AEI+BFG+CDH)-(CEG+DBI+AHF) and then talk about this formula. If you don't know what a determinant is, you probably don't know its nature. As far as this formula is concerned, it is mainly used to multiply any (non-zero) of a certain row (column) of the determinant by. The short vertical line outside is an absolute value symbol, and the long vertical line inside is a determinant symbol. A (X 1, Y 1), B (X2, Y2) and C (X3, Y3) are the coordinates of three vertices. According to the above properties, the formula becomes the negative one of the first line and is added to the second and third lines respectively, and the value of this determinant is actually the same. You can calculate the test according to the third-order determinant method at the beginning. By the way, I, J, k J and K are unit vectors of X, Y, Z Y and Z axes respectively. The determinant above actually represents this1/2 | ab ||| AC | Sina, which is equivalent to the formula S= 1/2 ac sinB. It's just the edge of angle A, because the outer product of vector AB and vector AC (the vector should be known) is the outer product, which is different from the inner product. The inner product is a number such as (the inner product is multiplied by a dot) ABAC = (x2-x1) (x3-x1)+(y2-y1) (y3-y1), and the outer product is a vector such as. J and K are both vectors, and its module should be | ab x AC | = | ab | AC | Sina inner product is ab AC = | ab | AC | COSA, so it is not very accurate to say that the short vertical line is an absolute value, but it is actually the symbol of vector module. At this point, the solution of this formula is completed. Finally, this formula is disgusting and has no practical effect. I don't know which bastard came up with it. Calculate AB and AC according to the formula of line segment length, calculate cosine value of included angle with inner product, and then convert it into sine value. Finally, the formula S= 1/2 bc sinA is applied. Compared with the formula using determinant directly, the whole calculation process seems to be much more complicated. In fact, in the case of simple data, the amount of calculation is far less than the former.

3. How to fill this third-order Rubik's Cube into a 3*3 (three rows and three columns) square box, and fill in the nine consecutive natural numbers of 1~9 without repetition or omission, so that the sum of the three natural numbers on each row, column and diagonal is equal? Usually, this figure is called the third-order magic square. If you fill the numbers in a square box of 4*4 (four rows and four columns). It is necessary to fill in 16 consecutive natural numbers in a 4*4 grid, so that the sum of the four natural numbers on each row, column and diagonal of the grid is equal, and the figure thus filled out is called a fourth-order magic cube. Rubik's cube is actually a puzzle game, not limited to the third and fourth order, but also the fifth and sixth order, ... until any command. Generally speaking. Fill in n*n continuous natural numbers, without repetition or omission (note that these n*n continuous natural numbers don't have to start from 1), and each number accounts for 1 grid, so that the sum of n natural numbers arranged in each row, column and diagonal is equal. We call this equal sum magic sum and n order, so the figure of numbers arranged in this way is called n.
