Hello, I’m Peter. Let me introduce my poster.
Last Sunday was Children’s Day. I went to the park with my friends. We had a picnic under the tree. We ate lots of delicious food. We drank some drinks. Tom sang a song. Kate danced. Meimei and Dongdong played games. I took some pictures and made a poster.

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
