Many years ago, Cheng Yi was a great teacher in China. And Yang Shi was one of his students. One day, it was snowing. Yang Shi and his classmates had some questions to ask his teacher for help. When they arrived at the teachers’ office, Cheng Yi was sleeping. They did not want to disturb (打扰) their teacher. So they waited out of the office. At that time, the snow was very heavy. After a long time, Cheng Yi woke up and found his students waiting outside the snow. He felt very sorry to them and asked them to come in quickly.
Later, people called the story “Cheng Men Li Xue” (程门立雪) . It shows the love from the students to their teachers.

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
