Hello, my name is Jack. I am from Canada. I go to school from Monday to Friday. I like Thursdays very much, because we have a computer class on Thursdays. We have lunch at school. Beef and potatoes are my favourite food. They are delicious and healthy. I’m very helpful at home. I can wash the clothes and water the flowers. On Saturdays I often read books. On Sundays I often do my homework. What about you? Can you tell me?

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
