Hello, I’m Sam. My family had a good time last weekend. Let me tell you. I went to the nature park to see animals. I took many pictures of them. The animals were so cute. My mother did housework and cooked dinner at home. My father read some newspapers in the evening. We ate dinner and watched TV together. That was fun. What about you? What did you do last weekend?

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
