715, Ji Cao Don't Six

. , the fastest update after wearing the book, she became the latest chapter of a big farmer!

As he spoke, he drew two Cartesian coordinate systems and parabolas on the blackboard, one with a parabola pointing up and one with a parabola downward.

The action of the New Year's painting is done in one go, and it is not muddy at all.

"Let's talk about the upward parabola first, you see that the opening of this parabola is upward, and the a in the quadratic function determines the direction and size of the opening of the parabola......."

Listening to the New Year's painting continue to talk about it, Zhou Shuhua gradually showed a look of disbelief.

Originally, she wanted to find mistakes in the New Year's paintings, but after talking so much about the New Year's paintings, she couldn't find any mistakes, and all the key points were clearly explained without any omissions.

Even if she speaks for herself, it's almost at this level.

With such a student, she didn't know whether to be happy or uncomfortable.

Listening to the New Year's painting standing on the podium and concentrating on the lecture, the students below were surprised to close their mouths.

Originally, they thought that they would make mistakes if they couldn't speak two or three sentences on the New Year's paintings, and even if they couldn't make mistakes, at least they would be incoherent.

This kind of thing happened in their class before, and the student with better academic performance went to the podium and couldn't hold back his words nervously without saying two or three sentences.

But as for the New Year's painting, I talked about most of the class, and I didn't stop for a moment.

"Students, what do you mean by that expression? Am I talking too fast to understand? Then let's talk about it again, this Cartesian coordinate ..........."

A teacher from another class who happened to pass by saw the New Year's painting standing on the stage lecturing, and stopped to listen out of curiosity, the more he listened, the more surprised he became, he had never seen a student give such a wonderful lecture.

Gradually, more and more teachers stood at the window outside the classroom, and they all heard about it and came to watch.

It wasn't until the bell rang at the end of class that the New Year's painting stopped and looked at Zhou Shuhua.

"Teacher, are you still talking?"

Still talking?

I'll let you give you another lesson, and I won't have anything to talk about!

"Alright, let's go back to our seats."

The New Year's painting stepped off the podium and walked to her place step by step, this time, the eyes cast at her by her classmates had turned into worship.

The New Year's picture is amazing!

This class has completely changed Zhou Shuhua's mind, originally thought that the relationship of New Year's painting would become a laggard in her class, but now it seems that New Year's painting is simply a genius, at least in mathematics.

Otherwise, she would not have been able to tell so many important knowledge points based on the knowledge she had prepared in the textbook.

However, there is one thing she still hasn't changed, even if the New Year's painting is a genius, it is also a problematic genius.

At this moment, Zhou Shuhua was already thinking about how to bring the New Year's paintings back to the right path step by step in the future.

Zhou Shuhua walked up to the podium and said: "I was very surprised by the New Year's painting classmates, I didn't expect her to give a lecture so well, this class was very successful, let us give her a little applause and encouragement." ”

The classroom immediately burst into warm applause, especially Ma Yun, who now fully believes what the New Year Painting said before, she is really a genius.

The long-lasting applause and the adoring eyes of the classmates made the New Year's painting a little embarrassed.

These are routine operations, and the basic exercises are not six.

This class happened to be the last class in the morning, and when the New Year's painting walked out of the classroom, it happened to meet Liang Jizhou's meaningful smile.

Liang Jizhou came in the second half of the class, when he saw several teachers standing at the window, and approached with curiosity.
