I had a good day today.
I got an A on my maths test. I felt very happy.
There was a new girl in our class. Her name is Jiayi. She likes playing basketball and listening to music. I was very excited to meet her. I hope we will be friends.
After school we went to a singing competition. We sang in the competition together. We won first place, so I felt very proud.

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
