Leijiacha etc students don’t know that there is a small trap in Kong Wei’s problem just now. Only by knowing the matching method can Mr. Li solve it. The so-called matching method is to make a binary linear equation become like the product of two algebras. In the 17th century, Europe is not mysterious, nor are Xingzhou and Daxia, but everyone has different time and methods.
Kong Wei went on to write that the blackboard is a ternary linear equation.
Although it is from binary to ternary, the difficulty of solving it is no less than from two-star warlock to three-star warlock or from primary school topic to high school topic. In the 17th century, high school students could not solve the ternary equation. At one time, some scientists claimed that the root of ternary equation was insoluble.
In the end, proving the solution of ternary equation involves several proofs, and adding negative numbers and complex numbers has not been accepted by the world, which is simply a mess
Of course, the level of warlocks in Xingzhou and Great Xia Xing has passed that difficult period, so Cheng Jinzhou easily wrote the solution of the ternary linear equation, which was awkward and hesitant
Kong Wei looked at Hui Ren and wrote a very general ternary linear equation.
Mathematics is a very strange subject. In this subject, students focus on particularity. First of all, consider whether it is round or square. They are the most special shapes in nature. There is a special way called average algebra. More general equations often mean more complexity and trouble.
By this time, Cheng Jinzhou is really stupid if he doesn’t test them in white.
But he still couldn’t figure out what the three four-level astrologers wanted to test out, so he hesitated a little-he wrote the answer anyway.
Kong Wei glanced at the note and said, "Mr. Cheng is convenient to record here. Why don’t you answer my questions?"
"Answer these?"
"Yes," Kong Wei threw herself into writing.
Two astrologers sat up straight.
As early as a year ago, Sin Chew had a unified understanding of the ternary equation, but the speed of solving the problem was always too slow and too slow, because their solution would have all kinds of complicated troubles.
But both mathematicians and astrologers need simpler solutions to ternary equations, and the demand has spawned many ways. Generally speaking, the better the method, the faster it will be.
It is precisely because of the rapid development of solving equations in recent years that astrologers want to know how much avant-garde knowledge Shengya has mastered, and it can be regarded as a confirmation of Cheng Jinzhou’s identity
They never expected that someone would come here with a higher-end solution than Sin Chew.
The quill pen whiteboard gently brushed the sound. The three astrologers had palpitations like the signature of a letter card.
Chapter three hundred and fifty Formula
After two or three hundred years’ development, the solution of cubic equation in one yuan has become a mechanized procedure, and students can work out the answer no matter how stupid they look at the formula.
Who would have thought that mathematicians would duel with cubic equations in one yuan 300 years ago?
Cheng Jinzhou’s three star magicians want to simply solve more than ten cubic equations as quickly as possible. In less than a minute, they are only slower than Kong Wei’s copying questions.
Tai Yu and Hui Renren looked at it for a while, and it was clear that Cheng Jinzhou came to set the result formula that was suitable for all cubic equations.
This discovery surprised and delighted them, and at the same time, they had some doubts-is it really possible to have a formula to solve all cubic equations, which seems to make many classic problems worthless?
Hui Ren couldn’t help but pick up his hands and answer it again, although he had already printed the figures in his mind.
How careless!
In addition to Cheng Jinzhou’s habit of listing negative roots, people don’t regard negative numbers as a number because they don’t.
Hui Renyuan’s firm idea seems to have wavered.
In the past few days, he specially sent people to Cheng’s home to inquire about the news, so that he knew that Cheng Jinzhou had little time to go out to study in the past ten years. So how did he become a holy cliff brother?
However, the fact is that Cheng Jinzhou has clearly mastered the solution of the equation, which has never been mastered by the Xingzhou Astrologers Association. So important a solution is unfair to the public. Who could it be except the people who contribute to the sacred cliff?
Hui people can’t help but think of the file mileage. It seems that Jia Sangong is lying in a hospital bed all the year round and hiding from people’s sight when he has enough rest every day. It seems that it is not difficult to suddenly appear a teacher during this period.
The more he thinks about it, the more he looks like a sacred cliff. People have all kinds of guesses, but there is no definite answer. It seems possible if he is taught by students at home. At present, Cheng Jinzhou seems to be doing very well, even though he is more like a bureaucratic aristocrat, that is his family property. Bad habits that can’t be changed all his life.
Jiang Huang and Kong Wei doubt that there would be no Huimin Renduo, and now they are even less skeptical. "Mr. Cheng, does your method have a certification process?"
It would be nice if ordinary astrologers could have a higher-order equation algorithm, unlike four-level astrologers who always think more.
Like the earth of the times, astrologers have been able to master all kinds of cubic equation solutions, which are not as simple and easy as Cheng Jinzhou.
Cheng Jinzhou shrugged and said, "It’s not perfect yet, but I will publish Science soon."
Where is his imperfection? The root is that he forgot to prove the cubic equation, and it is impossible to remember that there is a paragraph that is based on the ruler chart and several deductions, such as Cheng Jinzhou’s semi-suspended Ph.D. process in physics.
Maybe if you are lucky, you will pick it up from Xingmeng Library one or three times to prove that Jinzhou thinks so.
Star warlocks in Xingzhou can’t insist on letting Cheng Jinzhou go.
No, they speculated that Dr. Cheng returned to his room and considered the star array problem.
Zhuo Huan’s threat of sacrifice didn’t scare him, but it still gave him a wake-up call. When he really faced the four-level star warlock, he and Lu Xu did not have an advantage in joining the star array. In the future, it would be better for lovers to spend a lot of money to improve their strength now.
He is already a three-star warlock, and he can withstand the starpower up to 1 o’clock, so he wants to find a star array that can bear the starpower slightly and enhance the maneuverability of the combination.
Of course, the basic elements are indispensable. For example, if the star array bears the same star point, the high power of the star array is limited, and it is best to modify the current star array foundation.
So thinking about Cheng Jinzhou, he handed the request to the "senior businessman", and he couldn’t find anyone else to help him carve and design the star array.
I can’t respond until two days later, but I don’t know if the elder businessmen have cooked their hands at once. About three hours later, there will be information to update the star array with 350,000 yuan and redesign the star array with 120,000 yuan.
"So accommodating?" Cheng Jinzhou is used to being abused by customers and has long forgotten the myth that customers are emperors.
Wanted to think, Cheng Jinzhou sent information in the past and asked what functions can be added by updating the star array.
Re-engraving is a very troublesome thing, and it may reduce the ability to bear the star array. Astrologers will not change the star array easily unless necessary.
This time, the information will be returned very slowly, and it will take a long time to reply. What function do you want to add?
Cheng Jinzhou’s brain suddenly turned. His first thought was that Li Xianfeng suggested "pulse" and he wrote the request of "wave pulse" without much consideration.
From a mathematical point of view, pulse is a quite energy-saving attack mode, because it has little attenuation, high total energy value and fast launch speed, which is almost an ideal attack mode. Apart from whether it can attack the target, there are definitely advantages and disadvantages to upgrade it.
At 350,000 yuan, it seems that it is not too much trouble. Cheng Jinzhou returned the confirmation message without thinking.
Izu came out and was jealous. "I’m not ready yet, and you’re going to stab the star array again."
"You need too much materials," Cheng Jinzhou muttered two sentences. "Think about it. We only took beryl for a month and a half, but the result was not enough, and you didn’t let me buy it."
Yi Su was embarrassed and said, "It is also possible to reduce some systems according to my original design."
Cheng Jinzhou suspected that when he saw his horse, he woke up. This fellow turned out to be over-designed. He smiled two times. "In this case, I think it’s best to shrink to a minimum. When I have money, I’ll help you expand. It doesn’t matter before you say it. Now it seems that you have no less heart to tell me what you want to design?"
Izunai muttered something.
Cheng Jinzhou listened and denied trying to make Izu’s body with the least materials.
The materials he wants from Star Alliance are not cheap, not to mention that there are two cheap items occasionally in summer, and the quantity is also small, not to mention making the astrologers artificial.
