Chapter 188

The test paper for the final exam of the 17th level mathematics class, Gu Lu has not yet come out.

In fact, there is no need to be in a hurry about this matter.

The work of writing the test papers is all on Gu Lu alone, not like other public courses, where four or five teachers work together to give in to other teachers' time.

Gu Lu only needs to finish the test paper one week before the math exam.

............

In a blink of an eye, another week passed.

As for the examination schedule for students in the Department of Mathematics, it has been announced on the academic affairs system.

Needless to say, these courses are basically in-class exams.

As for the exam course, Biqi and their first exam was the university English course on January 15th.

After that, it is a compulsory course in politics, ideological character and cultivation, which will be held on January 17.

Advanced Algebra, Mathematical Analysis, and Analytic Geometry were put last.

The last analytic geometry exam is scheduled for January 26.

Five exam courses, the pressure on Biqi is not too big, but it is not small either.

After all, their goal is not to pass long live.

Instead, as much as you can, sprint towards a perfect score!

However, compared with some majors that "as long as you choose a good major, you will win the college entrance examination at the end of the year", and there are more than ten exam courses at every turn, their mathematics major is still happy.

The first half of their freshman year is their first semester in college.

The results of their learning will be tested by passing such a final exam.

Approaching the end of the term, no one dares to slack off!

Maybe if you're not careful, you'll be overtaken at the last minute, cornering.

............

The building of the number of hospitals, in Gu Lu's office.

Gu Lu took a sip of coffee while his fingers were on the keyboard and tapped quickly.

He is now working on the final papers.

As for the difficulty, Gu Lu had already planned for a long time.

Simplicity is impossible, never in this lifetime!

It's definitely going to be difficult, but it's not so hard that it's suffocating.

In this way, it can not only play a role in testing the learning results of students, but also not too much to hit the students' self-confidence.

Gu Lu was very thoughtful.

In this way, I am worthy of my approachable and amiable teacher!

After Gu Lu finished rubbing his hands, he began to solve the question.

Gu Lu divided the test paper into two parts, namely fill-in-the-blank questions and question and answer questions.

Looking at the several-score test papers in previous years, there is no fixed format, so I let Gu Lu, the teacher who wrote the questions, do it at will.

In Gu Lu's plan, there are a total of ten questions, each of which is worth four points, accounting for a total of forty points.

There are six questions and answers, each of which is 10 points, accounting for a total of 60 points.

The knowledge examined covers the limits of fractions, derivatives, integrals, unequal integrals, differential equations, etc.

The topic will not be over-outlined.

However, I will examine some content that is not in the textbook, but Gu Lu has added and emphasized in the class.

After pondering for a while, Gu Lu tapped his fingers on the keyboard and edited the topic.

[1. Calculation limit lim(n→∞)∑((n+1)^z,k=n^2)1/√k=_____]

[2. If x(n+1)=ln(1+xn) and x1>0 are known, then lim(n→∞)nxn=_____]

............

Gu Lu's question is very fast.

But then again, just the final exam questions at the freshman level really can't waste much of Gu Lu's brainpower.

In less than 20 minutes, the 10 fill-in-the-blank questions were completed.

Gu Lu picked up the porcelain cup, took a sip of coffee, and then began to ask the next six questions.

Or the principle of going from easy to difficult.

[11. Proof: lim(n→∞)∫(π/2,0)sin^nx/√π-2xdx=0.]

[12. Assuming x0=1,xn=xn-1+cosx(n-1),(n=1,2,......) , prove: when x→∞, xn-π/2=O(1/n^n).]

[13. Saying that γ(t)=(x(t),y(t)), (t∈belongs to a certain interval I) is the integral curve of the C vector field (P(x,y),Q(x,y)) on R, if x'(t)=P(γ(t)), y'(t)=Q(γ(t)), ?t∈I , let Px+Qy be non-zero everywhere on R, and prove that the integral curve of the vector field (P,Q) cannot be closed (except for single-point cases).]

............

As mentioned before, although the content of advanced mathematics and mathematics is much the same.

However, mathematics is more theoretical, and higher mathematics is more practical.

It is reflected in the questions, that is, most of the score test questions are proof questions, and most of the high math test questions are answer questions.

Of the six big questions Gu Lu came out, five of them are proof questions.

Only the last question is a solution question.

Don't think that proof questions are easier than question and answer questions, sometimes, the difficulty of proof questions will make people doubt life.

It took nearly an hour for Gu Lu to get out the test paper with a total of sixteen questions.

Then, it took another half an hour to write down the standard answer in another document.

After doing all this, Gu Lu went through the test paper from beginning to end, then touched his chin and fell into a short silence.

After a few minutes of silence, Gu Lu put his hands on the keyboard again, and knocked down three words with his ten fingers after the last question of the test paper, that is, the sixteenth question: additional questions!

That's right, after thinking about it for so long, Gu Lu still decided to add an additional question at the end of this set of test papers.

Additional questions are worth 10 out of 10.

Points will not be deducted for incorrect or non-answers, but points will be added for correct answers.

Of course, the upper limit of the score is still 100 points.

If the score exceeds 100 points, it will be counted as 100 points.

"In this case, you shouldn't have failed the course, right?" Gu Lu stretched, moved his fingers, and muttered to himself.

Click Save, Gu Lu got up, and said to himself, "Students, good luck to you!"

............

The end of the semester is approaching, and the circle of friends is becoming active again.

All kinds of superstitious koi, starry sky, and high-score spray swipes the screen in the circle of friends.

This group of college students is usually not superstitious at all, but at the end of the term, they will be caught and believed.

A friend of a two-book student: "I feel like I'm accomplishing an epic feat. I was only at the high school level, and it took me two weeks to complete a semester of college on my own. It's damaging to me!"

An ordinary student's circle of friends: "I thought that the review was to check and fill in the gaps, but after the review, I realized that it was Nuwa who made up the sky, and only to find out that it was Jingwei reclamation, and in the end, I found that Pangu opened a new world!"

The circle of friends of a student at a key university: "The end of the semester is approaching, I will start reviewing from now on, and I will rest for the exam." I won't go to waves, stay up late, or watch dramas. I'm not going to have fun, I'm not going to hunt women. I will hang the beam and stab the strands, and die and die. I am a statue in the library, a ghost in the study room. I am the horn that awakens the dawn, the lamp that shines at midnight, the eyes that watch the textbooks, and the soul that seeks knowledge. I dedicate my life and hope to the end of the term, tonight, night and night!"

Bi Qi's circle of friends: "Ahhhh To die, to die!"

Zhang left a message below: "Big brother, you are only a freshman, and the complex variable function is a sophomore course!"
