I am Lily. I am 6 years old. I have a best friend in my class. Her name is Mary. She is 7 years old. We are in the same school. Last year, her family moved (搬家) to Australia. I felt very sad. It was difficult for me to say goodbye to my best friend. But we often call each other now. Last weekend, she told me that she would come to see me this summer. I felt very happy. I know she likes eating apples. I will buy some for her. At the same time, we will go to the zoo to see pandas.

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
