Last Saturday, our class had a trip. We went to the mountain near our city. That day, the weather was great. We started at 7:30. On the way, we talked and sang. Soon, we arrived (到达). Wow! It was really a wonderful mountain. We were happy. Then we went to the top. Then we has a rest (休息). I looked back. Oh, my friend Alice was far from me. She was very tired. I waited for her and asked her to follow me. At about eleven, we ate some food and drank some water. I felt the food was very great!

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
