It’s May 23rd today. It’s sunny. We are going to the nature park. In the park, the trees are green and the flowers are blooming (开花). Some birds are singing. Some bees and butterflies are busy flying around the flowers.
We also do some activities. Jack and Tim are playing chess. Mary is drawing pictures. And some other classmates are going for a walk. I’m playing with a cute dog. Whose dog is it? It’s Miss White’s. We all have a great time today.

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
