六月,孔圣山迎来绽放期。各种荷花争奇斗艳,虽然有桃红的、粉红的,但是有纯白的、粉白的。荷花开得异样芬芳无比,引得不少游客前来赏花、游玩。木桥那边,几个女孩正撑着油纸伞和汉服在拍照呢? 置身荷塘之中,我不禁想起“接天莲叶无穷璧,映日荷花别样红”这句诗来。

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
