Dear Liu Yun:
I am happy to have a pen pal. I am in Australia now. Everyday, I had fun with my friends. On Monday we went to a restaurant. We ate good food. On Tuesday we went to a park. We flew kites. On Wednesday we went fishing. On Thursday we rowed a boat. On Friday we went to the Zoo and saw pandas.
I’ll visit China next month.

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
