I have four good friends. They are Amy, John, Sarah and Mike. Amy is in Beijing. She wears her blue gloves and yellow sweater. John is in London. It’s warm and sunny. He wears his white shirt and black pants. Sarah is in Sydney. It’s hot. She wears a pretty dress and sunglasses. Mike is in Moscow. It’s windy. He wears his brown coat.

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
