"Oh, I'm so stupid. After adding up WeChat, I didn't say three sentences in total."
Back in the dormitory, facing Peng Xiaofei's constant complaints, Ye Ming had no choice but to take out his mobile phone to prove his innocence.
"Look, the chat history is still here."
"If you don't look, you'll have the eye of a needle."
The classmate behind him who was playing on the computer turned around instantly: "Damn it, did you talk about something inappropriate for children? It's going to make you feel needle-pricked when you look at it?"
Faced with the teasing from his roommate, Ye Ming had no choice but to spit out the fragrance and climb into bed.
Teacher Chen had already pulled him, Qi Yumo, and a sophomore named Shen Ruhai into a small group, but the senior only said hello and said nothing again.
Well, the senior who joined the group in his sophomore year must be really busy.
Putting his phone under the pillow, Ye Ming opened the "Matrix Calculation" borrowed from the library, and then called silently in his heart.
"Ita"
"Ita at your service."
"What is the concept of matrix."
"Is a set of complex or real numbers arranged in a rectangular array."
"Good, build a basic matrix."
"Build complete."
Ye Ming nodded with satisfaction.
"Please explain."
"Solution failed."
Ye Ming: "..."
"Okay, let's continue from the basics. Where did I tell you at noon today?" Ye Ming put down the book, took out his mobile phone, and found "Junior High School Mathematics" posted by a middle school mathematics teacher on the official account. A complete collection of knowledge points.”
At noon, he had already taught Itta about elementary school mathematics and some knowledge points from junior high school, and even gave Itta a few questions to complete.
Naturally, the result is completely out of the question.
That's why he thought about whether he could directly instill advanced knowledge and let Ita summarize it himself.
Now it seems that if you take a big step, it is indeed easy to lose your temper.
"Definition of a right triangle."
"Very good, there is such a right triangle, the two right-angled sides are 3 and 4, and the hypotenuse is 5."
Ye Ming looked at the Pythagorean theorem, thought for a few seconds and then continued: "We define the numerical variables of these two right-angled sides as a, b, and the hypotenuse as c. Then..."
Ita gave a direct answer.
"aa+bb=cc"
Ye Ming immediately laughed: "You are stupid, you have learned to answer quickly, and you answered well. But we don't express the square of a in the form of a multiplied by a, but in the form of a2."
"By analogy, when the two right-angled sides are 5 and 12 respectively, what is the hypotenuse?"
"13. c=√a2+b2."
"Very good. Assume that the right triangle ABC has B as the vertex of the right angle. Taking B as the starting point, draw a line segment perpendicular to the hypotenuse AC, and the intersection point is D. The intersection with the midpoint E of the AC side is BE. Based on this condition, you simulate several Triangle, summary.”
Then Ye Ming saw countless right-angled triangle patterns of different shapes flashing through his eyes like lightning.
"BD²=AD·CD"
"AB²=AC·AD"
"BC²=CD·AC"
"BE=AC/2"
…
"Not bad!" Ye Ming laughed.
He has it all figured out now.
This ETA is really a "blank system".
Sora has powerful computing power, but no basic mathematical knowledge, so that in the beginning, it didn't even know the basic value of 1+1.
For a time, Ye Ming thought "she" was just a hot chick voice assistant.
With just a few words from Ye Ming, "she" was able to directly summarize the Pythagorean theorem, the projective theorem and the hypotenuse midline theorem of a right triangle.
All I can say is that as long as the rules and logic are in place, "she" is indeed powerful.
Then, the next step is to see how you train yourself.
"Insert the definition of right-angled trigonometric functions. Three points ABC form a triangle, where B is the right-angled vertex. The value of BC/AC is the sine function of angle A, denoted as sin a. AB/AC is the cosine function of angle A, denoted as cos a…”
Ye Ming called it hot iron and directly introduced the concept of right trigonometric functions to Ita.
"remember."
"Learn right triangles here first, and then learn non-Euclidean geometry later."
Ita: "What is non-Euclidean geometry?"
"What we are learning now is classical geometry, pioneered by Euclid. It is only applicable to planes, so it is also called plane geometry. When the graphics are in spaces such as spheres and curved surfaces, it is no longer applicable."
"OK."
"Continue, let's return to the algebra content, the system of linear equations in two variables..."
…
There is no doubt that Etta's learning speed cannot be described as amazing.
Ye Ming has no doubt that as long as he can express himself logically, there will be no problem with Eta's learning.
But Ye Ming finally stopped after teaching second grade mathematics and adding some bases for numbers.
After all, his energy is still limited.
Ye Ming put down his mobile phone, closed his eyes and rested his mind while chatting with Ita.
"Ita, what is your underlying logic?"
"have no idea."
"Is it based on quantum operations or binary calculations of 0 and 1? Well... let's put it this way." Ye Ming thought for a while and changed his approach: "When you were calculating, did you perform base conversion?"
"No."
"...No, or are you unaware of it?"
"have no idea."
"Okay, just wait, I will let you learn large-scale integrated circuits and qubits sooner or later."
"clear."
“And programming.”
"clear."
“Also theoretical mechanics, thermodynamics, electrodynamics, quantum mechanics.”
"clear."
"No, you don't understand..." Ye Ming sighed: "It's very tiring for me to teach you like this... Can you learn it by yourself?"
"Ita is currently unable to establish contact with its host's senses."
Hearing this, Ye Ming was suddenly silent for a few seconds.
"Ita."
"exist."
"Let's seriously discuss how you can synchronize my senses."
"have no idea."
Ye Ming was silent for a few seconds and suddenly smiled.
"Well, it's normal not to know. Because I haven't taught you physics and biology yet, you don't even know what electricity is, what bioelectricity is, or what signals are..."
"But it's okay, the days are still long."
"Let's learn math first. You must at least have a high school level and be able to help me solve equations."
As he spoke, Ye Ming picked up his phone and saw that the ACM group showed someone @himself.
——In the afternoon, he turned on WeChat message notifications.
It was from Shen Ruhai, a sophomore and their captain for this ACM competition.
"@lacquer and ink@叶明"
"I'm done. We'll meet later. Bring your notebook and have a look."
Then there was an instant buzz, and Qi Yumo responded with a message.
"I have no problem, look at Ye Ming."
Ye Ming glanced at the time on the screen. It was already eight o'clock in the evening.
Logically speaking, he should be going to the team's preparation hall or library at this time.
But now he wants to continue teaching Ita.
So he thought for a while and replied.
"It's eight o'clock, isn't it a little too late?"
"It's not too late. I have compiled a set of last year's school preliminary questions. If you haven't studied them, you can just use them for testing."
Ye Ming frowned.
From what it sounds like, it sounds like you are specifically testing yourself and the paint and ink?
After a few seconds of silence, he typed three words.
"See you there"
"Third floor of the library."
