Chapter 1443

Once in a while, someone was about to sob out loud, but to his boss Mo Cheng's deep and cold black eyes, Shengsheng swallowed the words to his mouth, covered his eyes and muttered: "I didn't see anything I didn't see anything... "

Si Mo City just left, Tang Ziyan then called him, want him to stick his own stick.

But he left without looking back.

Tang Ziyan was so angry that she had to hit Li Xiaoxiao.

"Xiaoxiao, how to do this problem?" Tang Ziyan spoke in a soft voice.

Li Xiaoxiao looked up at the topic and said, "seek the second-order guidance first."

Tang Ziyan's hand, which was intended to write, stopped again.

Yeah, that's right.

She had no idea what it was to get a second derivative.

Looking at her eat shriveled appearance, Li Xiaoxiao bent her eyes, inexplicably happy in the heart.

Li Xiaoxiao's steps are more detailed than that of Simo City, so it takes more time.

But soon, she worked out the answer, checked it again, thought it should be right, put down the chalk and went back to her seat.

Tang Ziyan saw that they had finished one after another, and their faces were livid.

Li Xiaoxiao, this cunning bitch!

Didn't you say no?

Why did you write so much?

What else is there to ask for the second derivative, is it deliberately embarrassing?

Tang Ziyan forced himself to take back his mind, looking at the big words under the title, only felt particularly embarrassed.

But her friend was better than her. Although she didn't listen to the class carefully, she listened to a few sentences. In addition, the title was simpler than Tang Ziyan, so she made a score of three or four.

So, there are four questions on the whole blackboard.

For a time, only Tang Ziyan's topic was blank, especially empty.

"How to do it?" Tang Ziyan had no choice but to hit his friends.

The girl looked up and shook her head nervously: "I can't, it's high mathematics..."

"Trash, you won't write anything yourself!" Tang Ziyan was very angry.

The girl is a little aggrieved: "I I happen to know a little bit about it. "

At this time, the teacher had already walked around the classroom and went back to the platform. First, she looked at Li Xiaoxiao and Sima Cheng, and then focused on the topic of Tang Ziyan and the girl.

Seeing that Tang Ziyan had not finished writing, the teacher immediately began to prompt him: "the third question is to seek the second derivative first."

As soon as the teacher opened his mouth, many people looked up.

Once again heard the word, Tang Ziyan's face became more ugly.

The teacher saw that she didn't write down for a long time. She frowned and said, "why don't you write?"

Tang Ziyan had to turn around and say, "teacher, I don't know what it is to ask for second-order guidance..."

The teacher was also a little surprised and frowned: "which department are you from? This is a very basic step. I just walked around the stage and more than 90% of my classmates did it. "

Tang Ziyan's face has been some hang not live, but still pretended to be calm and said: "I am art and Media College."

The teacher didn't have much reaction and said, "no wonder..."

Before Tang Ziyan had time to understand the meaning behind this sentence, he listened to the teacher: "well, you go back. Although it may not have any effect on you in the future, since you have come to listen to the class, I still hope you can gain something. Otherwise, it is self deception and meaningless to waste this time."

Tang Ziyan's face was blue and purple, especially ugly.

Until I got back to the stage and did a good job by the side of SMEC, I felt that the comparison of several questions on the blackboard was so big.
