Hi! I am Tom. I am from the USA. I am a pupil. But I don’t go to school, because of the coronavirus (新冠病毒). We have on-line classes (上网课) at home. So my study is my new classroom now. It’s small and clean. What’s in my new classroom? Let’s have a look. One computer, one desk, one chair, one schoolbag and many books…Look, there is a picture on the wall. That’s my brother Bob. He is tall and strong. He has short black hair. His hat is brown. I have a brown hat, too. We both like brown.

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
