Last spring, I had a spring trip with my friends.
We got on the bus at 7:30. After half an hour, we got to the zoo. Then we visited the zoo. At half past ten, we began to make dumplings, and we had our lunch at 12:00. After we had a rest, we rowed a boat at 13:30. Two hours later, we took pictures, sang and danced together. We had a very 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
