I’m Tom. Jim is my good friend. He’s younger than me. But he’s much taller. We usually do sports on the weekend. But last Saturday, he was at home and did his homework. Because his mother had a cold. Jim cooked breakfast at 7: 00. After breakfast, he washed the dishes. In the afternoon, he took his mother to see the doctor. In the evening, he did homework. Jim was so tired. But his mother was very happy, “Jim, you’re helpful. You’re a good boy!”

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
