I'm Tim. My grandparents live on a farm. I visited them with my parents last weekend. I saw many ducks, hens, pigs and cows. I helped my grandpa plant trees. I watered the flowers and trees. My grandma cooked the meals. The food was delicious. I was tired, but I was happy. 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
