Hi, I’m Jack. Last holiday my family had a good time. We went to the zoo to see animals. My father took many pictures for animals. The animals were so cute that may visitors liked them very much. My mother went to buy some food and we fed（喂）them. After we left the zoo, we found a restaurant and ate some fresh food. The weekend was fun!

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
