Dear Mum,
It’s sunny today. I’m at Willow Primary School. It’s big and pretty. There are many trees and flowers in the school.
I like science class. Mr William is my science teacher. He is young and funny. Cindy is my new friend, and she is my classmate (同班同学). Cindy is polite and clever. She is a good student. She likes maths very much. She often helps me with my maths.
I eat lunch at school. The food is delicious and healthy. My favourite food is tomato noodles, but I don’t like onions.
I study hard at school. I will go home this Saturday. Love you!
Yours,
Sarah

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
