If I could turn the clock back, I would apologize to Miss Wang for my rudeness or offensiveness. Miss Wang teaches us Chinese. She was pretty open-hearted and kindly. You could imagine a smiled young lady standing in the front of a group of troublemaking teens. One day, I asked Miss Wang several personal and rude question in class. She didn’t reply. Instead, she gave me a serious look. I thought her silence as an insult. After that unhappy experience I didn’t attend his classes any more. Missing her classes are a mistake and I feel very sorry. Every now and then this unforgettable memory appears vivid in my mind and I hope do something to make her feel better.

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
