In the science laboratory
Jenny is in the science laboratory at a school. She is sitting next to Dean. Jenny and Dean are in the same science class.
Jenny likes science. She likes Mrs. Bennett, the science teacher. She likes learning about different chemicals (化学品). The chemicals are in small test tubes (试管) and flasks (烧瓶). There is a lot of special equipment (设备) in the science lab.
Jenny and Dean are wearing special glasses. These glasses protect their eyes. Jenny is adding a chemical to a flask. The flask is on a burner (燃烧器). The burner makes the flask and the chemicals hot. Mrs. Bennett is watching Jenny.
Jenny and Dean make notes. They answer some questions about the chemicals. They write the notes and the answers in their notebooks.

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
