Jenny is my good friend. She is eleven years old. She comes from America. Usually she goes to school on foot, because her home is near. Jenny’s mother is a teacher. She goes to work by subway, because it’s fast. What about her father? Her father is a doctor. He goes to work by car.
On weekends, Jenny and I often go to the park. Sometimes we have a picnic. It is very funny.

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
