Last holiday, I took a big trip with my aunt. We went to Australia by plane. It was in August. We left Beijing on Aug 3rd. It was winter in Australia. But in Beijing, it was summer. I like there, because I like playing with snow. I went ice-skating there and took many pictures. I bought many presents for my friends, too. I was excited, but I was tired, too. I should go back to school and have a lot of rest.

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
