My school is different from a regular (平常的) high school. All the students at my school work on different things. The students in the science class are learning about plants and they are growing plants in a greenhouse. Some students are planting new flowers. Some students have been digging since this morning. Other students are cuing the bushes around the school.
The students have to build a new greenhouse because the old one is very small.
Next week, our parents are going to visit the new greenhouse, so some students are working to finish it. We want our school to become more beautiful.

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
