Yesterday was Children’s Day. It was my last Children’s Day. Because I am growing up (长大). In the morning, we had four lessons. Our teachers and students had a big lunch in the cafeteria (自助餐厅) together at noon. After dinner we saw a play. Then we had a party. The students sang and danced. We were very happy. I got a lot of gifts. My father and mother gave me a bike too. It’s a new bike. I liked it very much. What a happy Children’s Day!

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
