Hello. My name is Li Lei. I’m going to Yucai Middle School this September. I’m going to say goodbye to my primary school soon. I had a very happy time at school. And I made some good friends. I’m very sad to leave them. I think I will miss them. At the same time, I’m very happy and excited to go to a new school, because we are going to learn lots of new things. I like Maths, History and Geography. Maths is my favourite subject. I will keep on practising and be better at it. And I think I will go back to my primary school sometime!

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
