It’s a fine day. The sun is shining. The sky is blue. My family is on the beach. My father is swimming in the sea. The sea is blue. He can swim very well. My mother is sitting under the big umbrella. She is eating a hamburger. Near her there is a bag. The bag is my grandfather’s. He is sailing (驾驶) his boat in the sea. Kitty, my sister, is happy to collect (收集) shells. Now she has many beautiful shells. She is counting them. One, two, three... Oh, there are twenty shells. I am playing volleyball with some boys on the beach. What a funny and happy day!

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
