I liked swimming very much. But I couldn’t swim very well. My dad could swim very well. I wanted to swim very well. So my dad taught me. It was not so hard to learn it. The first time, I could float in the water. I was very happy. The second time, I could move in the water. I was very excited. The third time, I could breathe in the water. But the fourth time, I could not go swimming. Because I had a bad cold. I had a headache. I should stay in bed. Oh! My God! I couldn't swim!

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
