I’m Jenny. I am an American girl. I am a pupil. I have a friend in China. His name is Daming. Yesterday I got some postcards from him. From the postcards, I know there are lots of beautiful places in China.
Look! This is the Changjiang River. It is the longest river in China. It's more than six thousand kilometers 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 kilometers 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
