Hello, my name is Li Hua. I am a student in Lintong, Xi'an. Spring is my favourite season! The weather is warm and many people visit us in spring because of the Terra Cotta Warriors（兵马俑）. I usually climb Lishan Mountain (骊山) with my friends on the weekend. Sometimes we go on a picnic in the park. Please visit us someday and I am sure you will have 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
