Last summer holiday, I took a long trip with my aunt. We went to Australia by plane. It was winter in Australia. But in Beijing, it was summer. I played with snow. I went skating there and I took many pictures. I bought many presents for my friends, too. I was excited, but I was tired, too.

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
