Last Saturday, I had a picnic with my family. First, I went to the supermarket with my mum. We bought three kilos of apples, four kilos of bananas and five bottles of orange juice. Then we walked to the park. We arrived the park at ten o’clock. We saw fifty birds in the tree. I took a photo of them. My little brother played with his toy train. My father read books. And my mother talked with my grandparents. It was a very beautiful day.

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
