Chapter 57 (1/2)

”Use Lagrange's mean value theorem.”

Zhu Ziqi confirmed again and again that the sound came from Yehong.

She was stunned. Lagrange's mean value theorem was familiar to her.

By the way, it's an important theorem in higher numbers.

But ye Hong suddenly said this to himself, what does it mean?

Night Hong shook his head, directly from Zhu Ziqi's hand a pull over Gao Shu book, casually picked up a pen from the table.

”What are you doing?”

Zhu Ziqi was startled. She stood up directly and ran to Yehong to grab back the books.

But her action, however, stopped abruptly!

Through the line of sight, you can see that ye Hong is working hard to write, and soon wrote a series of problem-solving processes behind the problem that he has been stuck with.

Zhu Ziqi's eyes are first angry, then to silly eyes, and finally is completely attracted by night Hong's action.

”That's what this is about!”

”Ah, how can this theorem work?”

Three minutes later, Yehong handed the book back to Zhu Ziqi.

”Ding! Zhu Ziqi looked at Ye Hong with surprise and joy: ”how did you do it?”

You know, Yehong is only a senior one student. He can solve the problem of advanced mathematics in college easily. Can't he meet the legendary mathematical genius?

Night Hong spread out his hands: ”now you believe in the strength of this genius?”

Zhu Ziqi remembers Yehong's uncanny speed of turning books before. If he's a genius, he can really understand his unusual actions.

But she still felt a little incredible, so she took out a few questions to test Yehong.

The result is self-evident, night Hong all easy to solve, eyebrows do not take a wrinkle.

”I don't know what to say.”

Zhu Ziqi looks at Ye Hong like a monster, wondering if he is dreaming.
