Hello, I’m Jack. I went to Hainan with my parents on National Holiday. My grandparents live in a beautiful village in Hainan. We visited them. It’s far from here, so we went there by plane. We went to see the blue sea every day there. The beach was beautiful. We went fishing and went camping. My grandma cooked good food for us every day. The seafood is tasty. I really like it. We took many pictures. I was excited.

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
