Chapter 534 (1/2)

Xi Ying took a look at the blackboard.

This is the third question of a geometric proof.

This kind of topic usually appears in the last few big questions.

And the third small question of the last few big questions, the students basically will not answer.

Because it's too hard and takes too much time.

The math teacher obviously embarrassed Xi Ying because he just wanted to talk about how to solve the problem.

He wanted to let Xi Ying know that the classroom is very important now. She is the one who wants to sprint for the college entrance examination. She can't be so muddled down any more!

However, Xi Ying stood up from her position, went to the blackboard, picked up a piece of chalk and began to write.

It is not the first time that Yuan Bai has been on the blackboard.

But today's yuan Bai's handwriting is quite different from before.

In the past, I always felt that there was a small family spirit, but now, the dragon and Phoenix are dancing, and they are rebellious and free and easy, and they also carry a murderous spirit of bullying people.

It took Xi Ying five minutes to write a blackboard.

The first reason is that there are many necessary steps to prove the geometry problem, and the second reason is that her font is too bold, so it occupies the whole blackboard.

The math teacher was stunned.

It's not because Xi Ying can solve this problem, nor is she shocked by her sudden change of handwriting, but because!!

This kind of problem-solving method, is graduate students will do ah!

It uses a lot of formulas that can't even be learned in college mathematics.

This

The math teacher looked at Xi Ying strangely.

Yuan Bai, who has always been able to pass mathematics, suddenly put so much knowledge in his head?

And it works?

”Can I go out? Teacher. ” Xi Ying fulfilled her duty as a student and asked politely.

”You What are you doing out there The attitude of the math teacher changed all of a sudden.

Although he didn't understand what made yuan Bai suddenly become like this, he was honored to have such a talented student!

”Go around.”
