"Today we learned the basic definitions of the trigonometric functions sine, cosine, and tangent."
"Trigonometric functions are widely used in solving practical problems, such as measuring height, distance, and angle."
"When we want to measure the height of an unreachable object, we can use trigonometric functions to calculate it."
In that comfortable and relaxing lounge.
The boys and girls sat around Chi Jiujiu, and the small classroom of the three siblings was in its daily warm and comfortable state.
Chi Jiujiu's voice is clear and pleasant, like a yellow oriole flying out of a valley, or like pearls falling on a jade plate.
As the refreshing fragrance rises, the learning atmosphere becomes extremely strong.
Gong Lening suddenly asked a soul-searching question, "Mother, actually... can't we tell the length, width, and height of an object at a glance without measuring it?"
Chi Jiujiu: ...
This is a bit beyond the scope and ordinary people can't do it.
Chi Jiujiu coughed lightly and said, "Ningning, we must be humble. There are always objects that we cannot measure at a glance, so the best way is to calculate them mathematically."
After today's teaching.
Chi Jiujiu, Gong Lening, a lively little girl, and Gong Qixu, a gentle young boy, tell the legendary stories of famous people in the history of the earth.
Gong Chenyan went out to prepare dinner.
"My dears, let me tell you about Einstein, Newton, Hua Luogeng, Archimedes... They are all heroes who changed the world."
Chi Jiujiu was talking.
Gong Lening's eyes sparkled as she sighed, "Mother, they don't know how to practice cultivation, and their average lifespan is less than a hundred years, yet they've made so many great contributions. Scientists like Einstein... are so amazing!"
"Yeah, what about you guys?" Chi Jiujiu nodded.
After a pause, she asked the children, "Ningning and Xubao, do you want to make some contributions to everyone and become heroes praised by everyone?"
"But this great hero is not limited to scientific research."
“Every field has its own legend.”
"For example, in the business world, there are many entrepreneurs whose contributions are enough to change the world."
After she brought her children back to modern times.
First take the college entrance examination, then go to university, let them adapt to modern life.
After the children graduate, they will be allowed to choose which part of the family business they want to inherit and lead the Gong Group to produce more new products for the benefit of all people.
If one of the three siblings can "control" the entire family business.
How nice it would be.
In this way, she and Ajin can start their honeymoon.
Come on, babies.
However...looking at the smart, filial and sensible children in front of her, she was unwilling to force them to inherit the family business. Everything should be based on their interests.
She tried her best to divert their interest towards business.
After graduation, if the children are really unwilling to manage the family business, then she, as a mother, will have to burn herself out silently.
If it really doesn't work out, have a second child with Ajin.
In short, we can’t let grandpa continue to worry about the Gong Group.
Little girl Gong Lening shook her cute head and said, "Mother, I can make contributions to everyone, but I don't want to be a hero praised by everyone."
Gong Qixujun smiled, "Mother, I am the same as my sister."
Chi Jiujiu was slightly stunned. These kids had a very high level of ideological awareness.
"Why?" Chi Jiujiu asked with a gentle smile.
Gong Qixu replied, "Mother, if we become heroes, many people will pay attention to us. If that happens, we won't be able to secretly protect Father and Mother."
Chi Jiujiu heard this:???
No, babies.
Isn't it a little early for you to want to protect your parents? These little arms and legs.
And why do it secretly???
Gong Lening continued his brother's words, "Besides, we also want to be like mother, quietly doing our work well and contributing to everyone."
Chi Jiujiu coughed lightly, but this could not be described as "silently".
Today, the Gong Group is still relatively high-profile.
Chi Jiujiu said, "You are such good children. Mother is proud of you. No matter what path you choose, Mother will support you."
At this time, Shen Mojin walked in with food.
Gong Chenyan followed closely behind, carrying a basket of washed spiritual fruits.
The whole family sat together and enjoyed a warm dinner.
After dinner, Shen Mojin stayed with Chi Jiujiu for half an hour and then went back to practice.
The three siblings began to work on sharpening the handcuffs and leg cuffs.
The "sizzling" sound of iron grinding forms a symphony that resounds throughout the leisure room.
Considering bringing the children back to modern times, taking the college entrance examination, and going to university.
Chi Jiujiu smiled and asked softly, "My dears, have you ever thought about what major you will choose in college? Mother wants to hear your true thoughts."
At this moment, Gong Lening's eyes lit up.
She answered excitedly, "Mom, I love painting! Since I was little, I have been passionate about using a paintbrush to depict the world as I see it."
During the ten years that Chi Jiujiu was in a coma.
In fact, Gong Lening was attracted by Shen Mojin's painting.
Gong Lening continued, "So, I want to be a painter in the future, capturing beautiful things on canvas forever!"
The little girl in red gauze had a determined look in her eyes.
Chi Jiujiu is Liangran, majoring in fine arts, which is not bad.
Gong Qixu's eyes were firm. "I am very interested in medicine. I hope to become an excellent doctor and save more lives in the future."
Gong Qixu himself has wood spiritual roots and is more interested in treatment.
Chi Jiujiu looked at the seriousness and enthusiasm on her second son's face, smiled with satisfaction, and nodded slightly to show her support and encouragement for him.
Just then.
Gong Chenyan, who had been silent all this time, suddenly spoke.
He frowned slightly, and after some deep thought, he slowly said, "I want to study at the National Defense Academy and contribute to my country in the future."
This decision was not made on impulse.
Rather, it is based on the "pursuit" of justice and responsibility.
In fact, at first, Gong Chenyan planned to reach the peak realm through cultivation, and then venture into the world of cultivation, specifically to eradicate those demons and monsters.
However, he is only in the Golden Core Stage now, and this path is obviously no longer applicable.
So he changed his mind and chose to devote himself to national defense as a way to accumulate merit.
Hearing Gong Chenyan's words, Chi Jiujiu's heart couldn't help but move.
My eldest son actually has such great ambitions and aspirations!!!
However, as long as Yanbao works hard and keeps making progress, he will be able to realize his ambitions and bring positive impact to the country and society.
Then, Chi Jiujiu asked again, "Do you know what courses are required for these majors?" The three siblings shook their heads.
Chi Jiujiu decided to wait until she got back.
You should have a good understanding of the curriculum of each major and then give some suggestions to your children.
