How are you? I’m in London now. It’s great! It’s hot and sunny here. The water is warm. I can swim outside. Now it’s 6 o’clock. It’s time for dinner. I often have some fish and vegetables. What about you? What’s the weather like in Beijing? Is it sunny and windy? Can you fly your kite?
Love,
Dad

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
