I'm Mike. I'm an English boy. I'm a pupil. I have a friend in China. His name is Xiaoming. Yesterday I got some postcards from him. From the postcards，I know there are lots of beautiful places(地方)in China. Look！This is the Changjiang River. It's the longest river in China. It's over 6, 000 kilometres long. This is the West Lake. It's in Hangzhou. And this is the Huangshan Mountain. It's in Anhui and it's very famous. I like this one best. It's a picture of the Great Wall. It's more than twenty thousand kilometres long. China is so beautiful that I want to visit it some day.

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
