Chen Zhou thought about it for a long time, but he didn't think of what he could send.

Looking at the laptop in front of him, he was slightly distracted.

Yang Yiyi gave her a notebook, but he never gave this girl anything.

Ice cream?

, how can there be ice cream......

Even if he can deliver it, he will order a takeout now?

Chen Zhou shook his head and denied himself.

"Let's wait until I get back to school......

Chen Zhou made a decision at the moment, and he began to make the video.

With fireworks as a backdrop, choose commemorative photos and videos along the way, and intersperse them.

Accompanied by the above copy.

"Hmm...... What do you use to open this video?"

Chen Zhou thought of one thing, programming.

At the beginning, in order to insure the UPC competition, Chen Zhou once taught himself a little simple C++ language.

Now it can finally come in handy.

Chen Zhou smiled slightly, thinking in his heart: "It's always good to take precautions......

Fingers began to tap rapidly on the keyboard, doing a small program as I expected.

Chen Xiao happened to see Chen Zhou's mysterious smile, and immediately had some doubts, he reached out and quietly poked his cousin: "Brother Yong, what do you think is wrong with my brother?

Chen Yong glanced at it, shook his head, and said in a low voice: "I don't know, shouldn't the words of the two of us just now stimulate him?"

Chen Xiao said uncertainly: "Probably not, right?"

Chen Yong asked, "Is the relationship between the eldest brother and sister-in-law good?"

Chen Xiao shook his head and said he didn't know.

Chen Yong asked again: "How long have my eldest brother and sister-in-law been talking?"

Chen Xiao shook his head again and said he didn't know.

Chen Yong stopped asking and lowered his head to write his homework.

Chen Xiao asked, "Brother Yong, don't we care about my brother?"

Chen Yong glanced at him and said, "You don't know anything, how do we care?" Let's do our homework honestly, or if we talk too much, we will be beared." ”

Chen Xiao looked at Chen Zhou again, and felt that Chen Zhou should have no problem, listening to the sound of the keyboard, it was still relatively fast and powerful.

I decided not to do it, bowed my head and started to do my homework.

Chen Zhouzheng was engrossed in his own programming, but he didn't hear the words of the two.

If he hears it, then he will only think that the children are really too relaxed now, and the homework assigned by the teacher is too little, so he has to add it!

A simple procedure, and it didn't cost Chen Zhou much time to get it done.

Chen Zhou tried to click and run.

"Well, it works pretty well. From the running of the opening equation to the playback of the video, it doesn't seem very abrupt. The key is that this copywriting is very good, very creative, and Yiyi can understand it. ”

"By the way, we have to change the names of the programs and files......"

When everything was ready, Chen Zhou waited for it to get dark, and then sent the procedure to Yang Yiyi.

After dinner in the evening, Chen Zhou sent his cousin Chen Yong downstairs, hurried home, and ran into his house.

It's time to show the real technology.

Chen Zhou took out his mobile phone and dialed Yang Yiyi's phone.

"Hey, Yiyi, have you eaten well?"

"Well, just eaten, what about you?"

"I've eaten well...... That one...... Yiyi, let's use the computer video tonight, I have a piece of information to send to you, I want to discuss it with you. ”

"Okay, then I'll turn on the computer. ”

"Hmm. ”

The phone hung up, and Chen Zhou sat nervously at the table.

This was the only surprise he could think of for Yang Yiyi under such conditions.

Soon, Yang Yiyi boarded the chat software with a laptop and directly sent Chen Zhou a request for video connection.

Chen Zhou clicked to accept, and Yang Yiyi's screen appeared on the computer.

Yang Yiyi asked, "What kind of information is it?"

Chen Zhou smiled mysteriously and said, "Wait a minute, I'll send it to you." ”

As he spoke, Chen Zhou sent the results prepared in the afternoon to Yang Yiyi.

As Yang Yiyi clicked on the file to accept, as the file transfer progressed, Chen Zhou slowly became a little nervous.

Finally, the file transfer is complete.

Yang Yiyi looked at the strange file name and asked Chen Zhou suspiciously: "What is this? Did you send it by mistake? Why is the file name 'X??" +(y-?? √X??)?? =1’？”

Chen Zhou deliberately showed a confused expression and said, "It should be this, what is in the document?"

Yang Yiyi clicked on the file, and it was also an 'X?? +(y-?? √X??)?? =1' filename thing.

Without waiting for her to ask, Chen Zhou said again: "Is it a small program?"

Yang Yiyi nodded: "It's a small program, is this what you sent me?"

Chen Zhou pretended to be calm and said: "Well, this is some of the information I found, I need to download it through this program, you open it and take a look." ”

"Oh, good. Yang Yiyi responded, and double-clicked to run the program.

Chen Zhou's eyes were glued to the screen, for fear of missing any change in Yang Yiyi's expression.

"Wow...... This...... This one...... This is so beautiful, the equation automatically draws a heart...... Ah, how can there be ugly photos of you, haha......" Yang Yiyi looked at the video in surprise.

Chen Zhou finally breathed a sigh of relief, fortunately it was a surprise rather than a fright.

"Wow, Chen Zhou, this ...... This passage ...... Your life is my defining domain, your thoughts are my correspondence laws, and your smile is the sufficient and necessary condition for my existence and this......"

“...... If your heart is the x-axis, then I am the sine function, revolving around you, with the ...... receiving."

“...... A zero vector can have many directions, but only one length, just like me, you can have many friends, but only one of you......"

“...... I am to you like an exponential function based on the natural logarithm e, no matter how many winds and rains you go through to find the derivative, you will still be ......"

"Wow, how did you come up with this?" Yang Yiyi finally finished watching the video, and she looked at Chen Zhou with a smile.

Chen Zhou looked at Yang Yiyi on the other side of the video with gentle eyes, and said softly: "Although every day with you is Valentine's Day, this is the first Valentine's Day we have spent together after all, and I want to leave you a good memory." ”

Yang Yiyi's pretty face climbed into a layer of redness, and her eyes looked at Chen Zhou intently, for her, this was really an unexpected surprise.

Time at this moment brought the two people in front of the screen closer again.

"Hmph, have you used this trick to coax girls before? How do you know about this cardioid equation? And these sinusoidal exponential functions, you have been studying this every day?"

"Wronged, I've never coaxed a girl, I've only coaxed you. I racked my brains to come up with this cardioid equation...... This copy is also something I thought about for a long time before I wrote it......"

Looking at Chen Zhou's serious face, Yang Yiyi sneered: "Okay, I believe you." ”

Chen Zhou didn't do the project tonight, but chatted with Yang Yiyi for a long time.

This night, Chen Zhou also slept soundly, who said that science students can't be romantic?

Chen Zhou, who is a mathematics department, disagrees, mathematics is romantic, not just mathematics......
