Hi, I’m Bill. I’m twelve years old. I’m tall and strong. I like playing basketball. I like blue. I like spring best because there are beautiful flowers everywhere. I like to read storybooks. But three years ago, I was short and thin. I couldn’t ride my bike or play basketball. I wasn’t good at English. Then I changed a lot. Now I can ride my bike well. I play basketball every day. And now I can play basketball well. I often play basketball with my friends after class. I also do well in English. This makes me very happy. I think I can do many things. I’m a big boy now. What about you? Tell me your changes.

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
