一位渔夫出海捕鱼的时候,与一群海鸥渐渐熟悉起来。渔夫每次出海,上百只海鸥停在船头,跟他嬉戏玩耍。渔夫的父亲听说儿子有一群海鸥朋友,便要他捉几只玩玩。渔夫答应了父亲的要求。第二天,他带了一只大大的鸟笼出海,想去捕捉海鸥。可是海鸥都在桅杆上盘旋,哀哀悲鸣,没有一只肯落下来,过一会儿便全飞得无影无踪了。
我的感悟:______________________同类型试题
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
