That's the parametric equation for the cardioid.

He didn't use a series of software such as ecxcle and matlab for Lantian. He Qi gave it to him, and he wanted to draw it by himself.In order to get the most accurate graphics, I usually draw the blue sky for the exam, and I picked up the ruler.He started by carefully establishing the coordinate system, taking dozens or hundreds of values.

On a small piece of paper, he points one by one.When he hit the last dot, his hand stopped shaking.That is a perfect heart.

The piece of paper on which the equation was written was already crumpled, but it was treasured by the blue sky.He sandwiched the light blue paper into the thick dictionary.The dictionary is thick enough to protect that paper well.

I don't know when, Lan Tian started to study hard.The total score of Science in No. 750 Middle School and Senior [-] was [-]. He could only get over [-] points in the first half of the semester, but in the monthly exam in January, Lan Tian scored [-] points.

In No. 1 Middle School where there are so many masters, five hundred and seven is nothing. No.600 Heqi, with a total score of [-].There is a difference of one hundred and six between the two of them, the scores of the two biology subjects.There is a difference of [-] people among them, half a grade.There was a difference of fifteen in the numbers of their examination rooms, which was the distance of one floor.

It's okay, there's still time.Lan Tian said to himself silently.

Whether it is a weekly exam, a monthly exam, or a final exam.Before the exam, the blue sky does not turn the koi to pray for a high score.He only looked at the paper with the equation of the cardioid.This is his motivation and luck.

The first exam is Chinese, and the exam starts at 08:30, and it is now ten past eight.

It's time to pack up and enter the examination room.However, before entering the examination room, Lan Tian had to take out the blue paper from the dictionary and breathe in his luck.

Many people have had this kind of experience. They knew that a certain note was stuck in a certain book, but they couldn't find it after searching over and over again.Now, this happened to Lan Tian.

He frowned and searched for the first time, but couldn't find it.

He searched for it a second time out of breath, but still couldn't find it.

He searched frantically for the third time, but still couldn't find it.

Where?Will it disappear?

Lan Tian became anxious.

The situation here attracted He Qi's attention, he turned his head, looked at the dictionary, and almost knew what Lan Tian was doing.

"Page 570 two." He Qi said without blinking.

He Qi's voice had an extraordinary impact on Lan Tian.Hearing He Qi's unique voice, the impatience in Lan Tian's heart gradually subsided.

He didn't realize what He Qi said for a moment.

"Page 570 two." He Qi paused, then added, "The thing you're looking for."

Blue sky:! ! ! ! ! !

Lan Tian blankly followed He Qi's instructions and turned to page 570.This time, it was no longer densely packed English, but a piece of blue paper representing love.

How did He Qi know where this piece of paper was?Why does he know better than himself?Doubts flashed across Lan Tian's head.

"There are still twelve minutes." Seeing that Lan Tian had committed a foolishness and stayed where he was, He Qi couldn't help but reminded him.

"?!" In order for students to develop good habits, the school stipulates that they are not allowed to enter the examination room 10 minutes before the exam.The doubts that flashed in Lan Tian's head were successfully scared away.He Qi's examination room is on this floor, only 30 seconds away from their classroom.And Lan Tian's examination room is on the next floor, diagonally opposite to their class.

He hurriedly packed his things and ran all the way.

Behind, He Qi couldn't help but chuckled and shook his head, this fool.

Fortunately, Lan Tian arrived at the examination room within the stipulated time, and was not disturbed during the examination. Generally speaking, he performed well.

After the exam, it took only two days for the results of all subjects to come out.

Some are happy and some are sad.

Lan Tian's family belongs to the happy one.

Before New Year's Eve, He Qi received a gift from Lan Tian.Two little clay figurines are holding hands, one is He Qi, the other is Blue Sky.

This pair of clay figurines is particularly ugly, and it looks like they were made by novices.There is no doubt that the creator of this handicap is undoubtedly Lan Tian.

He Qi also said they were ugly, but he still kept the pair of villains well.This collection has been collected for ten years.

Ten years, ten years.

The development of modern society is changing with each passing day, let alone ten years.In ten years, many things can happen, and the changes will be great.

But for those who are familiar with He Qi, these ten years have brought He Qi only a more and more cold face.
