Last holiday, I went to a beautiful village with my grandparents. There were so many trees and flowers. The mountain was green. The air was fresh. The river was clean. There were lots of lovely fish in the river. I went fishing with my grandpa in the afternoon. In the evening, I could see so many stars in the sky. There were nice vegetables there. Our family enjoyed ourselves.

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
