Hi! I’m Joan. Summer is coming. I’m excited. Because there is a long holiday in summer. It’s the summer holiday. This summer holiday, I’m going to a summer camp. I’m going with 19 other students on July 7.
They’re going to be from the cities around China. We’re going hiking. We’re going to a forest. We’re going to learn about animals and plants in the forest. In the evening, we’re going to make dinner together. After dinner, we’re going to sit around the fire. We’re going to sing songs and dance together. I want to make new friends there. I will have a great and interesting summer!

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
