C61 You Piece of Trash

Shen Yi's face turned red at Ni Chenxi's words, "I didn't listen to any lessons before, so of course I don't understand now. Besides, what do I need you to do if I understand... "

Ni Chenxi seemed to realize that the sentence just now was a little too heavy for a girl, but he would never take the initiative to ask for forgiveness. He went forward with a straight face and pulled the paper over. "How can I not understand?"

Shen Yi hurriedly took out a water-like pen and drew circles on the paper, "I don't understand any of this."

After she finished drawing, she opened her big watery eyes and looked at him with great anticipation and pleading.

Ni Chenxi endured the "stupidity" that was about to come out of his mouth and looked at Shen Yi. Finally, he resigned himself to his fate and moved a chair over to sit on Shen Yi's right side. " Then listen carefully. I will only say these questions once."

Ni Chenxi paused for a moment and added, "If you don't understand or remember, then you have to promise me one condition."

Shen Yi did not care so much. The desire to improve her grades was too strong in her heart. It made her choose to ignore the latter part of Ni Chenxi's sentence. She kept urging, "Hurry up. Hurry up."

Ni Chenxi looked at Shen Yi, who was anxious like a monkey, and smiled. She was so easily fooled.

Since he had already said it, Ni Chenxi was also in a good mood. It was rare for him to spend enough patience to help Shen Yi open the questions word by word. The steps to solve the questions were carefully listed step by step. He then connected the various formulas and theorems. He only wanted to make Shen Yi dizzy. The more she fainted, the better.

Ni Chenxi thought of everything very well. With Shen Yi's mathematical 60-point theory and 90-point theory, she would be a piece of trash. Even if there was an English subject with almost full marks, her comprehension ability would only be at primary school. It would be extremely easy to use these complex formulas and theorems to knock her out.

However, reality proved that people's calculations were not as good as heaven's. The ideal was very realistic. Ni Chenxi did not have a good teacher, so the first triangular-shaped problem was lost.

Shen Yi heard a few questions and directly skipped over the triangular-function and flipped back, "I already know how to do these triangular-function questions. Just teach me the triangular-dimensional math behind it. I always use wrong theorems and principles for that thing. And still find out the relationship between the two sides. "

Ni Chenxi could not help rolling his eyes at her,... "Why didn't you say so earlier?"

Shen Yi smiled apologetically. "I was afraid that I would misunderstand, so I asked you to tell me your thoughts again. Now that I have confirmed the correct direction of my thinking, we can change the topic."

Ni Chenxi held his breath and flipped to the back. He did not give her a chance to catch her breath and drew two auxiliary lines on the long square. "The most important part of this question is to find the auxiliary line. As long as you draw the auxiliary line, all the relationship between the two sides will be clear at a glance. After that, we'll change to asking for the supplementary line and ask for the proper cutting value of the supplementary line. "

Shen Yi's eyes lit up when she saw the ancillary line that changed from rotten to miraculous. "So this question can be done like this. Why did the teacher not draw the auxiliary thread today? "

Ni Chenxi enjoyed Shen Yi's surprised expression. His eyebrows raised in contempt again. " Because teacher only taught the most common solution, and the method I taught requires two auxiliary lines to be drawn. That's why it's very hard for an ordinary person to think of it. "

After he finished speaking, he looked at Shen Yi with a gaze that said, "You earned it. I have already drawn the auxiliary line. Do you want to try to solve it yourself?"
