    ?

    Qian Ruimin's voice was not low, Qin Mian naturally heard it clearly, and his face suddenly sank.

    Seeing Lu Yue and Jiang Tiantian coming in, she restrained her emotions and smiled warmly.

    "Teacher Qian was just joking. The teacher heard that you got three questions right this time. It's amazing!"

    While talking, Qin Mian gave Lu Yue and Jiang Tiantian a thumbs up.

    Jiang Tiantian pursed her lips, her fingers tensed, "Old Qin, we came here this time to ask the third question of this math test paper."

    "Sit down first, I'll take a look."

    The test questions for the midterm exam of the National Joint Examination are not a secret.

    Even the Academy of Mathematics will openly display the topics, and all mathematics lovers are welcome to learn from each other.

    However, the answer was not announced.

    After all, mathematics is a subject, calling for multiple solutions to one problem.

    The answer is just a few of the feasible solutions.

    ?Announced in advance, it will restrain everyone's mathematical thinking and logical thinking ability.

    This is what the Institute of Mathematics does not want to see.

    The so-called reference answers on the Internet are also integrated by those so-called educational institutions.

    There is a certain degree of credibility.

    Qin Mian invigilated the exam for two consecutive days.

    Although the paper has been printed, it has not had time to do it.

    The third question is a piece of spatial analytic geometry.

    The maximum value of the moment of inertia of the investigated uniform ellipsoid around a certain line.

    The selection-based test questions did not follow the syllabus of the college entrance examination at all, and this question was seriously over the syllabus.

    The problem of the rotation of a uniform ellipsoid is extremely abstract and has high requirements on the spatial thinking ability of the human brain. It is also a problem that has plagued the mathematics community for many years.

    Qin Mian took out a piece of draft paper from the drawer, did the math, and the answer gradually emerged.

    Lu Yue and Jiang Tiantian looked at each other, and the frowns on their faces became deeper and deeper.

    There is no other reason.

    Lao Qin's method is generally the same as the reference answer, and the final result has not yet been calculated, but it can be foreseen that there must be little difference.

    "Old Qin, why can't you do this?"

    Lu Yue briefly sketched a few strokes on the paper, then stopped, with doubts that could not be hidden in her eyes.

    Qin Mian froze for a moment, frowned, thought for a moment, then nodded.

    The arc of the corner of the mouth couldn't stop rising, and he exclaimed, "It's completely possible to do this, and it's even simpler than my method!"

    This method is simply brilliant!

    Jiang Tiantian squeezed her fingers slightly, "Old Qin, but the answer we calculated is different from the reference answer."

    Lu Yue also said: "The reference answer is your method."

    "You guys sit and wait for a while, I will calculate the final result."

    The method Qin Mian used is extremely complicated to calculate, but it is also the easiest conventional method to think of.

    The numbers in the title are very complicated, and the root sign is covered with a logarithmic function.

    Lu Yue and Jiang Tiantian's method is a different one

    Li Yun came out of the canteen and casually glanced at the dean's office.

    I saw Lu Yue and Jiang Tiantian sitting on the sofa, clasped their hands together, and muttering.

    Also, Qin Mian was almost lying on the table, the pen in his hand was moving fast, and Qin Mian was in full swing.

    No matter how you look at it, how weird.

    The door was not closed, Li Yun leaned against the door frame, knocked on the door twice, and said softly: "Do you need Dad?"

    The story of Liyun giving up treatment directly after thirty minutes of the exam and lying on his stomach daydreaming has already been spread in Xiaocheng High School, and even the whole Xiaocheng.

    At first, Lu Yue wanted to ask Li Yun, but after hearing about it, she couldn't figure out Li Yun's level, so she came to ask Qin Mian directly.

    Before Lu Yue and Jiang Tiantian could react, Qin Mian raised his head excitedly.  (Remember the site URL: www.hlnovel.com
