My name is Jane. My grandfather is very careless. He is a very clever man, but he never remembers little things.
April 27th was my birthday. My grandfather said to me, “I’m going to your home, and give you a present!” I was very happy. I waited for him all day, but he didn’t come, so I phoned him and asked why. He answered, “Sorry, I went to go the other granddaughter’s house.”

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
