I'm Eva! I had a dream last night. I went to a park with my friends. The park was beautiful. There were flowers and trees everywhere. There was a long river. The water was clean and there were many fish in the river. I played football with my friends on the grass. We ran on the grass. We kicked the ball. Suddenly the ball fell into the river. We were worried. A few minutes later, Jim jumped into the river. He swam to the ball and threw the ball back on to the river bank. We played football again. We were happy.

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
