Summer holiday is my favorite holiday. Because there are many beautiful memories(记忆). My children and I visited Xi’an city last summer holiday, it was very happy. You can feel the long history of China. There are many interesting places. We visited the Old City Wall(古城墙)、the Big Wild Goose pagoda(大雁塔) and so on. Then we went to the Xiqing park. The park is very big and there are many places to play. We were tired, but we felt very happy.

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
