Yesterday was a funny day. I walked to Lily’s home in the morning. I studied English together with her. We read some interesting English stories.
Then I went to a park by bike. I flew a kite there. It was a windy day. Suddenly my kite flew into a lake. Acute dog saw the kite. He jumped into the lake and swam to it. A few minutes later，the dog gave the kite to me. I was very grateful(感激的) to him.

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
