Chapter 43 Descartes’ Cardioid Function
In 1650, on the streets of Stockholm, 52-year-old Descartes met the 18-year-old Swedish princess Christine.

At that time, Descartes was living a life of begging, and his only possessions were tattered clothes and a few mathematics books.One quiet afternoon, Descartes was sitting on the street studying mathematical problems as usual.Someone came next to him and patted him on the shoulder, "What are you doing?" Turning his head, Descartes saw a young and beautiful face, and clear eyes like blue lake water, as charming as the blue lake.She was Christine, the king's favorite daughter.

Christine was quick-thinking and had a strong interest in mathematics, and she had a cordial conversation with Descartes.

A few days later, Descartes received notice that the king hired him to be the little princess's math teacher.Christine's mathematics improved by leaps and bounds under Descartes' careful guidance, and they began to become closer.Descartes introduced her to a new area of ​​his research—the Cartesian coordinate system.Through it, algebra and geometry can be combined, which is the prototype of analytic geometry founded by Descartes in the future.

Under the guidance of Descartes, Christine entered the wonderful world of coordinates, and she became fascinated by curves.Being inseparable every day also made them fall in love with each other.In Sweden, a romantic country, a pure and beautiful love quietly sprouted.

However, it wasn't long before word of their romance reached the king's ears.The king was furious and ordered Descartes to be executed immediately.At Christine's pleading, the king exiled him back to his country, and the princess was placed under house arrest in the palace.

At that time, the Black Death was spreading across Europe.Descartes, who was in frail health, fell seriously ill shortly after returning to France.During the days when his life was counting down, he missed the warm smiling face he met on the street day and night.He kept writing to her every day, looking forward to her reply.However, these letters were intercepted by the king.

After Descartes sent Letter No. 13 to Christine, he left this world forever.There was no sentence written on this last letter, only one equation: r=a(1-sinθ).

The king thought that there was an ulterior secret hidden in this equation, so he summoned all the mathematicians in the city to the palace, but no one could solve the equation.He couldn't bear to see his beloved daughter depressed, so he gave her this letter.Christine was ecstatic when she got the letter. She immediately understood her lover's intention, found paper and pen, and started to draw the equation graphics, and a heart-shaped pattern appeared in front of her eyes.This curve is the famous "heart-shaped line".

Today, this famous formula was used by Li Shaochen and given to Lu Yining.

Lu Chaoyong secretly took out his mobile phone and searched Baidu, "Descartes' heart-shaped function."His face darkened little by little. That was his little lover, his little princess, his daughter who was afraid of falling when he held it in his palm, and was afraid of melting when he held it in his mouth.This little brat is so good at teasing at a young age, how can he be so great when he grows up?He looked at his wife angrily.The couple looked at Mr. and Mrs. Li again.

Wen Yashu felt ashamed.If she had a son, she would definitely applaud and shout. The key is that he is only ten years old.This is her educational failure.

"Shaochen, what does this mean?" Wen Yashu asked knowingly. She just hoped that her son could justify his story, even if he told lies with his eyes open.

Lu Yining was full of expectations, but found that the atmosphere in the room was wrong. Everyone seemed to have...blame for Li Shaochen in their eyes?
Li Shaochen smiled, and his smile was as warm as the sun, "Grace, this function is parsed out to be a heart shape. There is still a long way to go, and we all have to face it independently. I only hope that you, a kind-hearted person, will treat this world sincerely, and in the future And also be treated with sincerity by the world.”

The four adults were shocked and speechless.The child's mind is so simple.And they, after experiencing various social situations for a long time, have long lost their innocent hearts. They are really worse than even children.

　Recently, Hongxiu has given several recommendations.I was moved but also stressed.Because I didn’t save the manuscript.I have my own job and am usually very busy. I have to take care of my baby when I get home.So updating 2000 words every day is already very difficult.But since the platform gave me trust, I really worked hard to code and updated 3 chapters in a few days.Although realistic themes are niche and there are very few readers, I still appreciate the readers who are reading, thank you!
