Chapter 254 (2/2)
Because Sn ≥ so, EO ≥ OM, so tan θ 1≥tan θ 3≥tan θ 2, i.e θ 1≤ θ 3≤ θ 2。 No, that's it. It's super simple. ”
When Charlotte lost her pen, she felt comfortable.
For him, this problem is essentially similar to 1 + 1 = 2, which belongs to the category of mental retardation.

”Brother, are you so good at math?”
Jing Xiaoqian's mouth suddenly opened into an O-shape, such as West Tower 1, West Tower 2, line angle, line surface angle and so on. She is just like listening to the book of heaven.
”It's OK. When I'm too busy, I always do two sets of high-level papers to reduce pressure. When I'm on business, I always take calculus problem sets with me to play.”
Charlotte said with a smile:
”Oh, by the way, I'm very interested in topology, non Euclidean geometry and Diophantine number theory recently. Would Mr. Zhong be interested in studying them together?”
”Bang!”
Zhong Ye Rong suddenly slaps her hand on the table. With a deep breath, she is proud and tall
”Mr. Xia, please stop pretending. If you are really good, please solve this problem!”
With that, Zhong took out a thick notebook from the desk drawer.
After opening, there is a calculus proof problem on the front page.
The last 400 pages are all about the problem-solving process written by Zhong Yerong. However, until the end, she still failed to solve the problem.
”This is a question given to us by my tutor, Yu Cun, a professor of mathematics at Tianhua University, as a graduation gift when he graduated from our class. So far, more than 40 people in our class have been discussing the solution in the group every day. Eight years have passed, but there is still no result.
Mr. Xia, since you are so powerful, why don't you help me with it? ”
Zhong Yerong holds her arms, and her pretty face shows a touch of disdain.
When she offered this magic weapon, she couldn't get used to Charlotte's boastful appearance. She solved a simple function problem and thought she was something extraordinary.
”Well, this question seems to be interesting.”
Charlotte's eyes brightened, staring at the notebook topic, how many years, he did not come across to let him mention some interest in the topic.
”I hope you can play with me a little longer.”
Charlotte broke her finger, picked up her pen and began to solve the problem.
”Are you really going to solve it?”
Zhong Ye Rong was stunned for a moment.
Looking at Charlotte's serious brow, her pretty face turned red. They all said that when a man is serious, he is the most handsome
Just as she was daydreaming, she heard Charlotte scream.
”Ah, ah
”It's OK, Mr. Xia. This problem is really difficult. Even the mathematics professor of Songjiang University can't solve it. You have the courage to challenge it. It's worth praising.”
A smile appeared on Zhong Yerong's cheeks and comforted him.
”What are you talking about?”
Charlotte gave her a white look and threw the pen back into the pen holder. ”I've solved it. The answer is minus two. Damn it, it's less than one minute. Damn it!”
”Isn't there a topic on this planet that can make me think hard?”
Charlotte was holding her hair in agony.
”What?”
Zhong Ye Rong is a Leng, picked up the white paper in front of Xia Luo, quickly swept a few eyes.
In the process of solving the problem, she adopted a novel routine that she had never tried. The steps were omitted too much. Before she could understand some parts, Charlotte came to a conclusion. Only half of the paper was filled, the answer came out.
”Mr. Xia, Xiaoqian, you wait.”
Zhong Ye Rong hurriedly picked up the mobile phone, took a picture of the problem-solving process on the white paper and sent it to a mathematical discussion group.
