One day the famous American scientist Albert Einstein met an old friend of his on a street in New York. "Mr Einstein," said the friend, "it seems that you need a new coat. This one is too old! " " It doesn't matter," answered Einstein. "No one knows me here in New York."
A few years later, they met in New York again. Einstein had become a world famous physicist by then, but he still wore the same old coat. Again his friend tried to let him have a new coat. Einstein said with a smile, "There is no need now. Everybody here knows me."
1.Albert Einstein was a famous American scientist.2.His coat looked like a very good one.
3.Albert Einstein was wearing another new coat some years later.
4.His friend thought Einstein needed a new coat.
5.From the story we know Einstein put his heart into his study.

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
