我家的小狗阿汪特别活泼。白天总是跑来跑去,有时候还会跳起欢乐的圆舞曲。晚上睡觉,它非要窝里、窝外地和我玩捉谜藏,总该安分了吧,好像浑身都有使不完用不完的劲儿。妈妈说,阿汪的活泼个性,跟它是否喜欢主人有很大关系。

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
