I can really play with it

Chapter 147 Convinced

Sha Hui couldn't help saying "ah".

The glasses on the bridge of the nose are crooked.

What am I seeing?
What is she up to? ?

Why did the two elders say "ah" and then "ah" one after another?
The reason lies in Xiaoqian's answering process.

First of all, from the topic, Xiaoqian, who has only passed 5 minutes, is already working on the fourth question.

But this is not the most exaggerated, after all, doing it fast does not mean doing it right.

But what formula did she use in the process?

Signs for a bunch of trigonometric functions in sin, cos, process!

She uses the law of sines and the law of cosines!

Isn't this stuff learned in high school?
Sha Hui fell into doubt.

Is it moved to the front now?
impossible!

The premise of using the law of cosines and the law of sines is to understand trigonometric functions, right?
Can elementary school students understand this stuff?

What surprised Lin Qi was that he was different from Sha Hui.

He can see the answers to these questions at a glance!
Xiaoqian's result is exactly the same as what he "sees"!

And Xiaoqian obviously calculated some other things. Since Sha Hui gave a lot of conditions, any angle and line on these figures can be calculated.

It can be said that she is not answering the questions, she is simply showing off her skills, and she has completely solved the ins and outs of these figures.

Sha Hui went back to his computer to look at the reference answers to the questions.

The first three questions are exactly the same.

?

After another 5 minutes, Xiaoqian raised her head and handed the paper to Sha Hui.

He turned his head and gave Lin Qi a smug look.

Lin Qi instantly understood that this girl did it on purpose.

She is very smart. From the moment she saw the question given by Teacher Sha, she knew that she was called here to prove something.

So in the process of answering, she deliberately complicated the process, and solved a bunch of things that were not required in the questions.

The purpose is to tell Sha Hui that it is unnecessary for him to point out the questions she answered in class.

this girl.
Lin Qi also laughed.

Hidden merit and fame.

Lin Qi thinks that he should have learned it from that "Elementary Mathematics". In just two days, he has already learned the content of high school, which is terrifying!
"Mr. Sha, am I doing the right thing?"

Sitting on Fang Ru's lap, Xiao Qian looked at Sha Hui innocently.

"you"

Sha Hui seemed to want to say something.

"Well, that's right, it's your process"

"I have written the process, I should have written the process correctly, right?"

Xiaoqian continued to add.

Of course I know the process of your writing, but I didn't let you write about the process of high school!
Sha Hui was a little bit crazy.

Sha Hui looked at Lin Qi again.

Lin Qi quickly raised his right hand, facing Sha Hui with his palm:

"I guarantee that I didn't do these questions for her, she did it independently."

Isn't this nonsense! I can find a few more questions that just happened to hit you, right?

Sha Hui felt outrageous.

Sha Hui took a deep breath to calm down his frightened heart.Then he asked Xiaoqian very seriously:
"Qianqian, tell the teacher, have you really mastered these contents? It is the kind that needs to have a clear mind, not just copying it mechanically."

Maybe Xiaoqian felt that this question was very important, she put away her relaxed look just now, and answered Sha Hui very seriously:
"I really understand that elementary mathematics problems are actually to explore the relationship between actual quantities, but there are many methods.

There are many ways to solve the questions just now, for example, put them in a plane Cartesian coordinate system, and use coordinates to transform geometric problems into algebraic problems to solve, but they are essentially the same.

Teacher, if you still want to watch it, I can show you it again. "

What Xiaoqian said was completely inconsistent with the logic of what she could say at her age.

Sha Hui was silent.

Having said all of this, if you still say that other people's children are lucky or learning blindly, then you are too dull.

Sha Hui suddenly felt that it was a ridiculous thing for him to wake up people to answer questions every day in the past few days.

He has already transcended this level and wandered in the ocean of knowledge, and he forcibly gave him a rope to pull him back.

Humor!
I also criticized her for not liking the process of writing before. People are thinking about more advanced logic issues. Who will play with you and play every house!

Mathematics teachers are probably the most talented among all subject teachers. When a student has the ability to learn in advance and master it in advance, then she can not follow the progress of ordinary people!

Sha Hui thinks so.

"In future math classes, you can learn by yourself, use your own math books. I won't point you to answer questions, and you don't have to do the homework I assigned in class."

Sha Hui seemed a little lost when he said this.

A child who I am very optimistic about and likes has completely proved from the inside out that she doesn't need me at all. This feeling is really uncomfortable.
Now Sha Hui believes that the 10 minutes mentioned by the Lin parent just now should not be a joke.

"Then thank you Teacher Sha for understanding."

Lin Qi thanked Sha Hui very sincerely.

"it's okay no problem."

Sha Hui waved his hand, gently put his water glass on the table, turned around, and began to wipe his glasses with a glasses cloth, but his back looked a little sad.

At this time, a small hand pulled the corner of his clothes.

"Mr. Sha, can I ask you other questions in the future?"

It was Xiaoqian who leaned over.

"what?"

Sha Hui put on his glasses, turned around again, and looked at the child carefully, and found that she didn't seem to be comforting himself on purpose, her eyes were pure and full of sincerity.

"Of course, teachers exist to answer students' questions."

Sha Hui replied seriously.

"Thank you, teacher. I will come to the office to find you if I don't understand something in the future."

"No problem! As long as I'm here, I'll definitely give you an answer!"

Sha Hui suddenly cheered up.

That's right, other people's children don't need to learn elementary school content, but they still have to learn other content. My math teacher is not only good at elementary school math, but there is always something that can help, discussing problems with smart children, That is definitely a very pleasant thing.

That's why he cheered up just now.

"By the way, in about half a month, the school will select people to participate in the elementary school mathematics competition in the district. Those who advance in the district can go to the city later. It seems that they can go all the way to the national finals. Qianqian, do you want to participate?

I can sign up for you, and each class can nominate a student. I didn't plan to choose you before, but now it seems that it must be you. "

Sha Hui suddenly remembered this matter.

Xiaoqian's eyes clearly showed "interest".

But she still turned her head to look at Lin Qi.

"Don't look at me, just go if you want, I absolutely support you."

Lin Qi said.

Seeing Lin Qi's statement, Xiaoqian nodded heavily at Sha Hui:

"Ok!"
