(1)汉字充满了韵味,请你也选择两个汉字,照下面句子的样子,仿写一句话。
例:“笑”字令人欢快,“哭”字一看就像流泪。
(2)汉字像一群活泼天真的孩子在纸上玩笑游戏,像一朵朵美丽多姿的鲜花愉悦你的眼睛。(读一读,用加点的词语写话)

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
