Hello, I’m Wang Bo. I’m in Class Four, Grade Five. There are lots of peonies in our city. They are very beautiful in spring. Many people come to our city to see them in May. There is a river near my home, and there are some boats on it. I often fly kites with my sister. In summer, my brother and I enjoy going fishing in the river. My family often go for a picnic in the park in autumn. When it snows, I like making a snowman with my friends.

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
