After dinner, Chris Gray and others from the delegation of Country Y left the Jiu'an Science and Technology Park accompanied by Mr. Li Hongming.

Liu Hongming also told Liu Lin that he would come and see more when he had time.

After returning to his quarters, Abt asked the other three to go back to rest first, and followed Chris Grayling to his room.

"Mr. Chris Grayling, what do you think, Mr. Liu Lin's proposal. Abt poured two glasses of water, handed one to Chris Grayling, and asked as he sat down.

"The temptation is very high, but the cost is also very high, and I don't see the first proposal he proposed. Chris Grayling sighed, thought for a moment, and finally shook his head and said: "The price and gambling are too big, and the country will not agree to it, and I dare not gamble." ”

"Although the gambling is very large, the benefits are proportional and very operational. Abt disagreed with Chris Grayling, thought about it, put down the cup in his hand, and retorted.

"Chief Abt, you have a point, but no one dares to agree, and no leader dares to do so, unless he is a madman. Chris Grayling shook his head and continued: "If we win, our country Y will indeed become the hegemon of Europe in one leap, and even become the third pole of the world, but what if we lose, no one dares to bear the consequences of losing, and we can't afford it, so ......"

"Involving the lives of hundreds of millions of people, who dares to implement such a plan, even if it is 100% successful, no one dares to do, we are a country, stability is the most important thing. Chris Grayling looked at Abt and shook his head, leaning back on the couch.

"But......" Abt opened his mouth, and finally closed it helplessly.

Indeed, Chris Grayling has a point, no matter how high the full power is, if it fails, then it will become tens of millions of sinners in country Y, and no one dares to do such a thing.

"That's it, but the second thing Mr. Liu Lin said, I think it's very operational. Chris Grayling drank up the water in the half-drunk cup in one gulp, put the cup on the table, and continued: "This time, Jiu'an New Technology has ordered about 15 billion experimental equipment, and these equipment are not within the scope of Batumi, although we have no profit, but we can make some requests to Jiu'an Technology, which is not excessive." ”

Abt thought quietly, waiting for Chris Grayling's next words.

"If the operation is good, it is also a very big improvement for our country, Jiu'an Technology's sewage treatment system, no system, has now been introduced, the sewage treatment system is only two, and the wireless system is only three companies, but we are the first to be authorized, this is our advantage, if we agree to his second plan then we ......" Chris Grayling said: "When I return to China, I will slowly sum up with the Prime Minister how to expand this advantage." ”

"Those old men in China are stubborn, and they shouldn't agree to this plan. Abt was very unoptimistic, shook his head and poured cold water on Chris Grayling.

"That's not necessarily, when we agree to sign the contract, it's actually equivalent to agreeing to the plan. Chris Grayling saw that Abt didn't understand, so he explained: "There is an old saying in China, driving a sheep is also driving, and driving a group of sheep is also driving. Why not. ”

"But ......"

......

"Boss, does the Y Congress agree with your suggestion just now?" After the Y country and Li Hongming and his party left, Gao Bi asked suspiciously.

"The first suggestion should be disagreeable, and they don't dare to agree, but the second one should be fine!" Liu Lin leaned on the sand to make himself more comfortable, and said to Gao Bi: "Manager Gao, you use the second plan I proposed, make a plan, how can we maximize our interests!"

"Okay, boss, I'll arrange it right away!" Gao Bi sat up straight and nodded!

"Don't go in the wrong direction, country Y and country M have always worn the same pants, let's take this opportunity to make their two countries face each other and have a discord!" Liu Lin emphatically explained: "This time you do it yourself, it's best not to go through the hands of others!"

"......" Gao Bi and Jiang Rong looked at each other puzzled.

"Country Y is also an old industrial power, although many fields are not as strong as our country, but there are still many more powerful than us, especially in terms of basic technology and projects, plus they are in Europe, and far away from the European continent, so many things are very convenient to operate!" Liu Lin explained to the two: "Our country's basic industrial foundation still has a lot of deficiencies!"

"However, what should I do if country M finds out? It is a well-known fact that country Y and country M can be said to wear the same pair of pants. Gao Bi instantly felt that Yali Mountain was big!

"This contract is to see what to do with country Y and country M, Manager Jiang is not very demanding in the sewage treatment plant, but there is one thing you must pay attention to, the magnetic field generator of the sewage treatment system, the two shafts of the core components, are absolutely not allowed to fall into the hands of outsiders, which you must pay special attention to. Liu Lin said very seriously, and added a sentence after speaking: "As for others, whether you can make money or not, I don't care about you, if you really can't keep it one day, you will destroy it directly, and people are not allowed to have problems, I don't want the family members of employees to come to the company, crying, making trouble and hanging themselves." ”

"Boss, I understand, absolutely no problem. Jiang Rong's heart trembled, and he hurriedly promised.

"Okay, that's fine, I won't say anything about how to do it, you can do it yourself, I just need to ask the result! As long as the sewage treatment plant is controlled in our hands, it is none of our business whether country M and country Y make trouble. After Liu Lin finished speaking, he turned to Gao Bi and said, "How is the negotiation in country R now?"

"It's the same as before, it's useless, and they're like it's a waste of time now. Gao Bi reported.

"What the hell is going on in Country R?" Liu Lin frowned, thought for a moment, and then said to Gao Bi: "Manager Gao, did they mention any conditions? or do they have any different actions." ”

"Not yet!"

"Then ignore them for now, now that the company has more things, they can drag it if they like to drag it, and the main focus is still on the side of country Y. Liu Lin couldn't figure it out after thinking about it for a long time, so he just didn't care, he just talked about it, and didn't talk about it.

After the establishment of the joint venture company of the precision industry group, it will be much more convenient at that time.

......

After the delegation of country Y left, Liu Lin explained that if there was no major incident, he should not contact himself, so he devoted himself to the life of brushing books.

Z(W) has a second continuous derivative, and Z′(0)=0,lim

W→0，Z=（W）

（W）＝1，+（？）

There are four variables:

A, Z(0) is the maximum value of Z(W).

B, Z(0) is the minimum of Z(W).

C,(0,Z(0)) is the inflection point of the curve y=Z(W).

D,Z(0) is not an extreme value of f(W), and (0,Z(0)) is not the inflection point of the curve y=Z(W).

First of all, according to the tenth legend of Montessori: Z′(0)=0 shows that Z=0 is a stationary point of Z(W), and in order to judge whether it is an extreme point, only the sign of Z"(W) needs to be determined.

Because

Lim-W→0，Z″（W）

/W/

=1, substituting the fourth variable of the third series of Zhou's concept, we can get that the concept of infinitesimal can be known, lim=W→0

f″（W）＝0．

Because Z(W) has a second order continuous derivative, and lim

x→0

Z"(X),/x/=1>0, by the limit of the number holding, there is δ>0, for any 0 <0, so that there is Z"(W)>0.

Thus, according to Mavmunkath's formula, it is concluded that any x∈[-δ,δ] has Z'(W)≥0.

Since Z"(W)≥0, it can be seen from the definition of the inflection point that (0, Z(0)) is not y=Z(W) and the inflection point is |x|

Liu Lin looked at the extra answers, leaned back in the chair, took a deep breath, and looked up at the roof in a daze. How could it be wrong?

It doesn't make sense, what the hell is the problem?

This question trapped me for a long time!

Montessori 10th legend, Zhou's concept 3rd series 4th variable, Mavmont's formula...... This is a completely standard answer, but how can the final answer be wrong?

Liu Lin finally didn't give up, and picked up the pen again to calculate.

What's wrong with it?

MMP Liu Lin is ready to start roaring, now that mathematics is only in the middle of the first book, it will be difficult to become like this, and it will not let people live in the future!

Time has passed, and it's already a heavy period, so I really don't think my time is worth anything!

I didn't believe it, Liu Lin took a few deep breaths and picked up the book again!

The idea of solving the problem: Suppose we are looking for a value of Z', and import the Mavmonkath formula, that is, the functional relationship between two variables is X, and find the derivative of one variable to the other.

The known condition gives us the derivative of Z(1/x^2) versus x, and the relation between these two variables is W, and the fourth variable of the third series of Zhou's concept gives us the derivative of two variables with Z relation.

BY CONVERTING WX TO X(1/W^2), WE CAN DERIVE THE DERIVATIVE OF Z(1/W^2) TO 1/W^2 ACCORDING TO THE GAUSS FORMULA, AND THE FUNCTIONAL RELATIONSHIP BETWEEN THESE TWO VARIABLES IS Z.

Wait, it's good to see what's wrong, Liu Lin looked surprised.

I excitedly picked up the pen that was thrown on the table, and wrote directly on the scratch paper (brush, brush, brush)!

Z'(X)=-lim to the power of x.

Z'(X) = Z power -1/W of W. X, where the extreme point is the point where the derivative is zero.

Z'(X)=-1/x=0.

Z＇（W）=W．X -1 =0。

m=1／e。

Z(x)=1//-lim=.e's W-1-power-lim.

Z(x) = x-1 power of e-lim.

After entering Green's formula, the W>1 Z'(X)>0 function is an increasing function, and the 0

When x<0 Z', the (x)0, Z(X)>0.

That's it, Liu Lin saw the final answer, and the whole person who was happy lay back, and a happy smile finally appeared on his face, it's really not easy.

I almost didn't worry about myself, but now it's finally solved!

Flattered!!!

After looking at the time, it's only eleven o'clock, and there is still an hour before the meal, then, let's continue!

Just when Liu Lin kept brushing the questions, far away in the Atlantic waters of western Africa, a ship with ocean-going A038 written on its hull was advancing forward with the wind and waves!

"Captain, is it Whale Harbor?" a voice of surprise came from the cabin.

"Okay, I know, let's work hard, I'll take you to the dock in a while, I'll take you to make a good wave!" a loud voice roared out of the cabin.

"Okay, let's take us around in a moment. ”

"Arrived, arrived, be careful to approach the docks. "The jumble of voices kept coming out.

"I finally saw the land, I've been floating on the sea for half a month, and my mother can finally open the fish!" A middle-aged uncle who looked like an African looked at the dock not far away and shouted!

As soon as he finished speaking, there was a burst of laughter.

"You guys, how much better than me!"

“......”

"Mr. Chen, according to your request, now that the ship has stopped at Walvis Harbor, do you have anything to explain, and what are your plans in terms of itinerary. Li Haiyang, the captain of Ocean A038, said on one deck to a tall and thin young man wearing a formal suit and a pair of sunglasses.

"Captain Li, don't worry, I'll give you an explanation before I get off the dock!" Mr. Chen, looking at the dock that is getting closer and closer, he has been carrying his heart for a month, and this time he can put it down.

The people on this ship don't know what is on the ship, but they know it, and now country M is still looking for it all over the world!

Ultra-large high-precision five-axis machining center.

This is not a joke, if you are caught by country M, then you can say goodbye to your life!

As soon as the boat docked at the dock, a big man wearing toad glasses and a bronze antique jumped onto the deck, followed by a middle-aged man wearing a white T-shirt with gold-rimmed glasses.

"Who are you?" Li Haiyang saw someone walking onto his freighter, and hurriedly walked over and asked!

"Hello, may I ask who is Mr. Chen Feng?"

"I'm Chen Feng, are you?"

"You don't want to know who you are for the time being, but you can call me Old A, this is Mr. Li Haiyang, the captain of the A038 freighter, right?"

"Okay, let's get over there. Chen Feng glanced at the bow deck, no one was special, it was convenient for conversation, and he was not afraid of others eavesdropping, so he pointed out.

"Good!"

PS: Tomorrow weekend, the old rules, Wan more, next time it's May Day!
