How is everything? We all miss you. Last week, I went to Hawaii with my dad and mum. It is really a wonderful place. We talked on the beach, swam in the sea, ate a lot of seafood and watched a very beautiful dance. It was so hot in Hawaii, but we had a good time there. Here is a photo for you. Hope you like it. Please write to me soon.
Yours,
Tom

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
