Hello, I’m Tom. Welcome to my school. This way, please. My classroom is on the first floor. It’s clean and nice. Our library is on the second floor. Many students are reading books in it. Oh, we must talk quietly. The music room is on the third floor. Some students are listening to music in it. The art room is on the fourth floor. Some students are drawing pictures in it. Look! That is our playground. Are the students dancing? No, they are doing kung fu. They are cool!

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
