| × × × × × × Dear Mum, How are you? I had fun with my cousin Alice. On Monday we visited our grandparents and ate good food. On Tuesday we went to a park with our friends. We flew kites and went fishing. We took many pictures. On Wednesday and Thursday we studied English together. We read funny tongue twisters(绕口令). I’ll be back home on Saturday! Miss you very much. Yours, Sarah |

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
