Last summer holiday, I went to Jinan with my parents. Jinan is the capital of Shandong. It’s in the east of China. There are lots of springs in Jinan. So it’s called the Spring City. We visited Darning Lake, Baotu Spring Park and Spring City Square. We also climbed the many photos there. And we stayed there for seven days. We had a good time.

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
