Good morning, everyone. It is my honor to stand here and share with something about traveling. Which I’d like to convey is that to travel is also to learn. Take my journey to Xi’an for example. Previously, I do learn something about the city from books and TV programs. Therefore, I didn’t know what wonderful it was until I was there in person. When traveling, we can feel the surrounding with our own eyes, noses and so on, thus broaden our horizons. The picture took on the Great Wall is good reminder of my happy days during my stay in Xi’an. So everyone, seize every chance or you will start an amazing journey to learn.

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
