How are you? I’m writing to you in my school. This school is great! There are nine hundred students in my school. I like the teachers. The other students are very friendly. I learn Chinese from them.
There is a small river behind our school. The water is clean. We can swim in it. There are no classes on Sundays. I am at home and watch TV. My father and my mother go to shops on Sundays. They all like China. I can speak Chinese now. I can write my name in Chinese. Please write to me soon!

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
